ESPHome Switches restarting + LED1 (gpio14) problem - restarting SOLVED

Hello,

I have the same "problem 1" than the one initially reported by @Goran Skular

My setup:

• Switch: Athom SW112EU (2 gangs EU wall touch switch)

• Firmware: ESPHome (config: https://github.com/tarontop/athom-configs/blob/main/athom-sw02.yaml) NB: I changed this in the config for reverting the state of the leds when relays are turned on/off:

  
  

  # Button LEDs (1.0 = Blue / 0.0 = Red)
  - platform: esp8266_pwm
    pin: GPIO14
    inverted: false
    id: led1
  - platform: esp8266_pwm
    pin: GPIO1
    inverted: false
    id: led2

• Wiring: (see bellow picture)

Problem:

Whe I push button 1; relay 1 is switched on and the light bulb is powered; but I can see the leds of my device flickering ~3 seconds. Then the switch reboots (sometime crahes and requires hard reboot) and the light buld is powered off.

I tried several light bulbs ranging from 17w to 23w; and it works in no neutral mode with both Tasmota and ESPHome on 1 gang (sw111eu) and 3 gangs (sw113eu) switchs; but it doesn't work at all with 2 gangs (sw112eu)

I tried another capacitor; but problem is still there.

I activated DEBUG logs to MQTT; but didn't find anything interesting:

switchs/athom/athom-2gang-switch/logs [D][binary_sensor:036]: 'Button1': Sending state ON
switchs/athom/athom-2gang-switch/binary_sensor/button1/state ON
switchs/athom/athom-2gang-switch/logs [D][binary_sensor:036]: 'Button1': Sending state OFF
switchs/athom/athom-2gang-switch/binary_sensor/button1/state OFF
switchs/athom/athom-2gang-switch/logs [D][light:036]: 'Light1' Setting:
switchs/athom/athom-2gang-switch/logs [D][light:047]:   State: ON
switchs/athom/athom-2gang-switch/logs [D][light:036]: 'LED1' Setting:
switchs/athom/athom-2gang-switch/logs [D][light:047]:   State: ON
switchs/athom/athom-2gang-switch/logs [D][light:085]:   Transition length: 0.5s
switchs/athom/athom-2gang-switch/light/led1/state {"color_mode":"brightness","state":"ON","brightness":255,"color":{}}
switchs/athom/athom-2gang-switch/light/light1/state {"color_mode":"onoff","state":"ON","color":{}}

What can I do to fix this problem ?

NB: I tried same setup with "neutral" mode and it worked. (but I unfortunatel cannot use this setup in my house)

I think the 2 different 2 gangs switchs I tester have some hardware problem, preventing them from working in no neutral mode.

I also sent an email to Athom support for inbestigation and maybe after sales actions.

Thank you very much for your appreciated help

Best regards

I got it working using both GPIO14 and GPIO16 at the same time. With this config the transition is not working correctly when turning on lights (second transition starts after first one ends), but it's ok when turning it off (both transitions starts at the same time - correct). I just set transition time to 50ms and I'm done with it.

  # Button LEDs (1.0 = Blue / 0.0 = Red)
  - platform: esp8266_pwm
    pin: GPIO14
    inverted: true
    id: led1
  - platform: esp8266_pwm
    pin: GPIO1
    inverted: true
    id: led2
  - platform: esp8266_pwm
    pin: GPIO16
    inverted: true
    id: led1b
  ...
  # Button LEDs
  - platform: monochromatic
    name: "${friendly_name} LED1"
    #disabled_by_default: true
    id: light3
    output: led1
    default_transition_length: 50ms
    on_turn_on:
      - light.turn_on: light3b
    on_turn_off:
      - light.turn_off: light3b
  # additional for LED1 to enable bright blue    
  - platform: monochromatic
    name: "${friendly_name} LED1b"
    disabled_by_default: true
    id: light3b
    output: led1b
    default_transition_length: 50ms
      
  - platform: monochromatic
    name: "${friendly_name} LED2"
    #disabled_by_default: true
    id: light4
    output: led2
    default_transition_length: 500ms

After our test, there is no problem, you try the firmware in this link https://github.com/tarontop/athom-configs/blob/main/athom-sw02.bin

Thank You, but the led light still doesn't turn blue. When it's off it is dimmed red as it should be, but when it's on (both using old GPIO14 or GPIO16 from v2) it just goes off.

On tasmota I am using GPIO14 and it works, on ESPHome it doesn't. It just goes off for a light1 led status (led1).

The solution to problem 2 is as follows

https://github.com/tarontop/athom-configs/blob/main/athom-sw02_v2.yaml

Problem 1 is solved.

Problem 2 with led1 blue light missing is only present on ESPHome firmware. On Tasmota everything works well.

Final Tasmota configuration (2-Gang):

{"NAME":"Athom SW112EU","GPIO":[576,321,0,32,225,33,0,0,0,224,320,0,0,0],"FLAG":0,"BASE":1}

Update: I tried with tasmota firmware. And there is the same problem. Device keeps restarting when relays are turned on.

I bought 46 of them, paid customs and everything... but it seems it is hardware related. Maybe it works correctly with a neutral line, but I am using a no neutral line configuration as I am unable to have 'with neutral' configuration.

What can I do now?

Tasmota template I was using (for a 2 gang switch)

{"NAME":"Athom SW112EU","GPIO":[158,53,0,17,22,18,0,0,0,21,52,0,0],"FLAG":0,"BASE":1}
