Hope someone can help me. I have an esp32-cam connected to home assistant. I want to connect a dfplayer mini to the esp32-cam module. My question is - which pins can I use for the uart tx connection? I can’t get my yaml file below to work, so can only think I have used the wrong pin to send commands to the dfplayer. I know it plays the mp3 file by manually triggering it. My yaml code is

api:
  reboot_timeout: 0s
ota:

esp32_camera:
  external_clock:
    pin: GPIO0
    frequency: 20MHz
  i2c_pins:
    sda: GPIO26
    scl: GPIO27
  data_pins: [GPIO15, GPIO18, GPIO19, GPIO21, GPIO36, GPIO39, GPIO34, GPIO35 ]
  vsync_pin: GPIO25
  href_pin: GPIO23
  pixel_clock_pin: GPIO22
  power_down_pin: GPIO32
  resolution: 640X480
  name: camera.doorbell
# DFplayer configs
uart:
  tx_pin: GPIO15
  baud_rate: 9600
  
  on_press:
    then:
      - dfplayer.set_volume: 25
      - delay: 150ms
      - dfplayer.play: 1
      - switch.turn_on: led1

Hello. I would like to measure voltage on A0 pin and also VCC battery voltage. If I program it in C++, it works. But following configuration only sends one mqtt sensor - I suspect that one definition overrides the other. Is there any other way how to define both sensors?

sensor:
  - platform: adc
    id: pracka2_vcc
    pin: VCC
    name: "Pracka2 VCC"
    retain: true
    update_interval: 30s
    accuracy_decimals: 2

  - platform: adc
    id: pracka2_pr
    pin: A0
    name: "Pracka2 Photo Resistor"
    retain: true
    update_interval: 30s

Hi
I am trying to make a project with a nextion display and esphome.I would like my d1 mini to change pages created on my nextion display, managed to make it change two pages with this code:

globals:
 - id: nextion_page_id            
   type: int
   restore_value: no
   initial_value: '0'
display:
  - platform: nextion
    id: display_nextion
    update_interval: 5s
    lambda: |-
      if (id(nextion_page_id) == 0) {  
      it.goto_page("main");
       auto time = id(sntp_time).now();
          it.set_component_text_printf("hour","%02d",time.hour);
          it.set_component_text_printf("minute","%02d",time.minute);
          it.set_component_text_printf("date","%02d",time.day_of_month);
          it.set_component_text_printf("month","%02d",time.month);
          it.set_component_text_printf("year","%02d",time.year);
else 
       it.goto_page("page1");
}
id(nextion_page_id) = !id(nextion_page_id);

Can somebody help me-being a total newbie –on how to change more than two pages?
I tried something like this but did not work.

display:
  - platform: nextion
    id: display_nextion

I’m planing on modernizing my meat curing chamber and have a wemos d1 mini that will control the fan based on humidity but I also wanted to add a bunch of loadcells to monitor the weightloss!

Question is, can a bunch of hx711 boards share the same sck? I’ve tried Googling and the responses are varying so I thought I’d ask here.
This is the plan right now:

Has anyone successfully flashed one of the lilygo ethernet POE boards? Using their programmer board, and have tried various ESP flashing tools on several different machines.

I’ve successfully flashed other boards and the data light is flashing on the programmer board so I don’t think it’s a com port issue.
It feels like the board isn’t going into flash boot mode, despite me trying every combination of the boot and reset buttons.

Hey guys,

Ive migrated some devices from Tasmota to ESPhome after reading that its better integrated, better supported ect. And its just awful, keeps dropping off the network every 20s or so. These is the same for all three devices that are a mixture of different types (one magic home and two kogan filament bulbs)

Have I made a mistake here? should I switch back? Or is it a wrong setting?

I’ve opened a topic under “Hardware” here at the forum where I am trying to open up the LAN control function that Yeelight suddenly has shut down on demand from Xiaomi. I do not have much coding experience but have been able to pull the FW from my bslamp2. Is it possible to add ESPHome support for this device?

Hello guys and girls,

i want to make a lamp that incorporates 4 leds for mixing a desired colortemperature.

• 6500k
• 1800k
• amber (580nm)
• red (660nm)
  this would make it possible to get the whole range of color temperatures (1000k->6500k) with high CRI.
  But i don’t know how to program that.
  I did already generate a lookup table that includes the needed power levels for each led for a given color temperature.
  I think i need a custom light component that reads the table and sets the outputs accordingly.
  However i don’t know how to use the provided software pwm (esp8266) with a custom light component.

Does anyone have a idea how to realize my idea?
I could also use 4x monochromatic lights+dummy light and make a automation in HA that reads the dummy light and sets the 4 monochromatic lights to a desired value, but this seems like a bad solution.

thanks

Hey Guys -

I’m trying to set up a NodeMCU which includes an IR Transmitter & Receiver, but having some difficulty. I got the receiver working just fine as hitting a button on my fan IR remote yielded the below log:

[13:46:57][D][remote.jvc:048]: Received JVC: data=0x0CF3
[13:46:57][D][remote.lg:053]: Received LG: data=0x0CF331CE, nbits=32
[13:46:57][D][remote.nec:068]: Received NEC: address=0x0CF3, command=0x31CE
[13:46:57][D][remote.pioneer:144]: Received Pioneer: rc_code_X=0x0C8C

When putting the below info into the yaml, uploading it, and triggering it via dashboard button; nothing happens, though.

remote_transmitter:
  pin: D0
  # Infrared remotes use a 50% carrier signal
  carrier_duty_percent: 50%

switch:
  - platform: template
name: Tower Fan - Power
turn_on_action:
  - remote_transmitter.transmit_nec:
  address: 0x0CF3
  command: 0x31CE
  - platform: template
name: Tower Fan - Power2
turn_on_action:
  - remote_transmitter.transmit_jvc:
  data: 0x0CF3

As you can see, I tried both the NEC & JVC codes assigned to different templates for testing, but neither worked.

I also tried facing the IR transmitter & Receiver to each other, then triggering. Logging yielded the below in the log when I actually expected to see what was logged with the initial capture from the remote…

[13:51:39][D][remote_transmitter:066]: Sending remote code...
[13:51:39][D][remote.raw:041]: Received Raw: 229

Shouldn’t the above match the output the receiver displays when original remote is read?

Hardware wise, I have a 100ohm resistor between the IR LED’s anode and of course ground going to ground of the NodeMCU. Although I I couldn’t see the IR LED with my phone camera (even briefly) when triggered, I can see it when I connect the resistor to 5V. To ensure that something was coming across D0, I replaced the IR LED with a standard blue one which did briefly light when triggered. Aside from this, I’ve tried a couple different resistors, powering the NodeMCU via 5V battery instead of USB, + verified its not a range issue.

The IR LEDs are rated 1-1.5V and are linked here.

I’m at a loss. Any suggestions? Thanks!

Hi There,

I have four windows that have Truth’s Sentry II Window Opener. I’m trying to integrate them into Home Assistant with ESP-Home and use a NodeMCU.

This is the manual/PDF for Sentry II

Page #17 shows wiring diagram for Open/Close using HPI contact closures.

I’m not a pro, but my understanding is maybe I can use relays controlled by a ESPHOME to open/close? 12V Relay

What I’m struggling with is the Open/Close status. It says the status is reported as a relay and uses 120V 0.5 A On Page #23

Status output function:
• The status output functions as a relay. When the output is
closed (relay contacts closed), the window is fully closed. When
the output is open (relay contacts open), the window is not fully
closed.
• Feedback output (contact closure) maximum ratings:
Rated Load: 0.50 A at 125VAC, 1 A at 24VDC
Minimum Load: 1mA, 5VDC
Max. operating voltage: 125 VAC, 60 VDC
Max. operating current: 1A
Max. switching capacity: 62.50 VA, 30W

How can I use ESPHome/NodeMCU to detect this. Would 120V not fry the device?

TL:DR Looking for confirmation on the Open/Close using 12V relay, as well looking for solutions to monitor open/close status

Thanks

Hellow friends
Thanks for hearing my problem, please give me the solution for the LED Effect

First: I´m very new to HA, and I have no experience in programming. But I like to think I´m slowly improving. Anyways, please keep any answers as simple as possible.

I want LED indication for my water level in the tank. my wifi is not really good with HA, she wants to check the water level. so I want to WS2812b led to show the water level.

WS2812b LED is connected with D1 mini (through ESPhome )

Here is the program in D1 Mini
ESPHome

Here is how I converted my ultrasonic Sensor value to a percentage using Template

HA Template

Sensor:
  - platform: template
    sensors:
      percentage:

          {{"{:.1f}".format((0 - states('sensor.sensor.ultrasonic_sensor')|float) / -1.5) }} 

I want WS2812b led to show the water level by this value “water_level_in_percentage”

I’ve converted my Zemismart moonlamp to esphome, and it works very nicely.
But I’ve just been told that I’ve accidently swapped cold and warn GPIO on it.
How do I test if it’s correct, or I have swapped it?
I have three LED’s, cold, warm and rgb, they are setup like these outputs:

    warm_white: output_warm_white
    cold_white: output_cold_white
    warm_white_color_temperature: 2700 K
    cold_white_color_temperature: 6000 K

So it’s easy for me to fix it, but how do I test if the cold and warm are the right GPIO’s?

Hey!

I work on an indoor Hemp grow and have been having issues with my water tank level sensor getting inaccurate readings. After debugging the issue for a while I finally found the issue but I don’t know how to fix it yet. I am hoping someone here will be able to help me out.

The tank level sensor I am using is the AquaPlumb from Vegetronix. This device gets calibrated for the “no water” and “full water” levels and outputs a voltage from 0v (empty) to 3v (full). I already found the ADC on the esp8266 to be rather inaccurate so I order the ADS1115 to try and fix this issue and it actually did make things far more stable. The problem is that we are pulling hundreds of amps with our grow lights and when they turn on/off it causes my voltage readings to fluctuate quite a ridiculous amount (the tank will read empty because it is and the lights will all turn off causing the voltage to spike on the mains which then makes the sensor read “full tank” and vice versa when the power goes off).

image1481×435 27.8 KB

So how can I combat this? It seems my transformer output moves with the input voltage (which totally makes sense) but I need a stable 5v reference for my ADC. I thought that possibly using a 120vac to 12vdc transformer then using a buck-converter or linear voltage regulator to take that 12v down to 5v but I am just curious if this will actually work. I did try moving the sensor to an independent power supply and tied the grounds together for reference and still had issues.

Esphome code:

i2c:
  sda: D2
  scl: D1
  scan: True
  id: bus_a

sensor:
  - platform: ads1115
    multiplexer: 'A0_GND'

how can I make sure that there are no 2 overlapping activations of the switch.turn_on: PortaBlindata call?

I wish it was not possible to activate the momentary switch twice until it has finished all its execution

hi all,

i have one neopixel led mounted in my extractor hood in the kitchen,
i want it to be, red, green, blinking red, etc etc AND able to call up these state’s when various thing happen in the house (other nodes)
I came up with this workaround to get the state’s, but unable to give them an ID.
I thought giving the different state’s an ID then I would be able to make some services.
ans also I think it should be much easier to get a desired state, now I tweaked the “strobe” function…

So I want to use a smart switch to control some smart lights which means that I don’t actually want to have the relay turn on of off based on the clicking of the switch.

I managed to find a configuration for my switch here:

and I actually managed to get it working by removing the ‘- switch.turn_off: relay’ line from the template platform but I would like to try to simplify the config file so I’m wondering whether there’s an easier way to do what I’m looking for.

Basically, I just need the button press to report the status of the switch (on or off) to home assistant. I guess I need to use the LED on the switch to determine whether it’s on or off or does it make more sense to just toggle the state in HA with each press of the button.

I’m looking at the basic switch integration but it looks like I have to specify the “platform” and I can’t have it be just a toggle reporting it’s state to HA.

I would also love to setup a fall back on the switch whereby it operates as a normal relay toggle if the switch can’t connect to HA (either because it’s offline or because the wifi is down). Is that even possible?

Hi everyone. I am new to this forum and to using microcontrollers. I have home assistant running on virtualbox and also have an arduino mega with a couple of sensors connected to it. I was able to get readings from all the sensors on serial monitor in arduino ide. Now I would like to get the readings on arduino to home assistant.
Right now I only have the arduino mega and a nodemcu, is there any way I could use the nodemcu to send readings from serial monitor to home assistant? I looked at some tutorials on connecting arduino with nodemcu via serial communication but none of them were showing how to send the data to home assistant. Is there any way of doing this with what I have? If it is too complicated I would prefer buying something to make it easier :slight_smile

Thanks

Hey everyone,

i currently trying to flash a custom fw on a growatt Wifi stick (Link) to get rid of the growatt cloud and have up to date information’s in HA.
The construction of the stick is rather simple:
An ESP8266 07s connected to a I2C real time clock, a USB Serial converter, some led’s and a voltage regulator from 5V to 3.3V.

Real time clock: NXP 8563T
USB Serial converter: xr21v1410

After removing two 0Ohm resistors between the ESP TX/RX Lines and the USB Serial converter I was able to dump the original FW and could Upload a small test FW from esphome:

esphome:
  name: "test"
  platform: ESP8266
  board: esp07

logger:
  level: DEBUG
  baud_rate: 9600

wifi:
  ssid: MY-WIFI-SSID
  password:  MY-WIFI-PASSWORD

ota:
  password: "test1234"

The upload and hash verifying went thru successfully. But after a reset of the ESP nothing happened.
On the serial console on baud rate 38400 I saw the following message:

mpfff… It seems that the bootloader can not find the start address so I flashed back the original FW and saw the following on boot:

2nd boot version : 1.6
SPI Speed : 40MHz
SPI Mode : QIO
SPI Flash Size & Map: 32Mbit(512KB+512KB)
jump to run user1 @ 1000

OS SDK ver: 2.0.0(e271380) compiled @ Mar 30 2018 18:54:06

So here everything is fine. The first thing that what caught my eye is the SPI Mode and Flash Size.
I tried to override these setting with the following configurations (As described in the documentation: here and here):

esphome:
  name: "test"
  platform: ESP8266
  board: esp07
  platformio_options:
    board_build.flash_mode: qio
    board_build.f_flash: 40000000L

logger:
  level: DEBUG
  baud_rate: 9600

wifi:
  ssid: MY-WIFI-SSID
  password:  MY-WIFI-PASSWORD

ota:
  password: "test1234"

after compiling and flashing it I got the error message

system param error, use last saved param!

on boot.

After some googleing around I have found this (now closed) Issue: https://github.com/esphome/issues/issues/1638
In this issue it is stated that the ESP8266 07 has 1MB of flash and the ESP8266 07S 4MB of flash and i am using the 07 in my configuration. So something is odd there.

After listing all boards with the prefix “esp07” in the ~/.platformio/platforms/espressif8266@2.6.2/boards/ directory I have only found the 4MB version:

6171003 4 -rw-r–r-- 1 tom tom 781 Feb 3 22:00 /home/tom/.platformio/platforms/espressif8266@2.6.2/boards/esp07.json

Ok then. It seems that i am not running the bleeding edge version of PlatformIO. Fine for me. Everything seems to match. Even “esptool.py flash_id” reports back:

Manufacturer: 20
Device: 4016
Detected flash size: 4MB

But why can’t I get the esp to boot and why does the status message of the original FW say

SPI Flash Size & Map: 32Mbit(512KB+512KB)

??

The Datasheet of the flash claims that it as a size of 64MB (Link).

Do anybody has an idea was going on here?

I love using ESPHome and I’ve used it with hardware displays (like the ssd1306). It works very well for multiple pages and using fonts/text. I really want to make a chart of temperature history (like history graph in Home Assistant but on a hardware display), to show like last 12 hours or something. I’ve looked though the docs and it doesn’t seem to be supported. Does anyone know how to go about doing that with ESPHome?
