Search for WIFI Wall Plug in EU

skycryer · April 2, 2020, 8:35am

Hi, I am looking for cheap WIFI Wall Plugs that can be used with ESPHOME, can measure Power and are available in EU (Best in Germany). I Have Order 2 different Tasmota usable Plugs but both are not really run like I want. So I can use them over ESPHOME but I can not get them working so I can switch them on/off by pressing the button on the device. I tried the automations script, changed the GPIO settings, but without luck. So maybe the config are wrong or it is not fully supported.

So maybe someone here an recommend a Wall Plug that runs with ESPHOME, can measure power and can be switched on/off by pressing the button on the device.

The latest one I tried was this one

What ESPHome config have you tried?

If you post that someone might be able to point you in the correct direction.

The Shelly Plug S ?

Shelly Plug uses cloud or not? I would prefer not to use something that needs cloud access.

With stock firmware you can choose to use cloud or local mqtt
It has an esp, so you can flash tasmota, or as you asked, esphome.

It looks like you have your “power button” and LED the wrong way round and also according to that link the relay is GPIO15 not 14. Also the CF and CF1 pin’s are wrong.

switch:
- platform: gpio
  name: "${plug_name}_LED"
  id: blue_led
  pin: GPIO0

- platform: gpio
  name: "${plug_name}_Relay"
  pin: GPIO15
  id: relay
  restore_mode: ALWAYS_ON
  on_turn_on:
    - switch.turn_on: blue_led
  on_turn_off:
    - switch.turn_off: blue_led
  
binary_sensor:
  - platform: gpio
    device_class: plug
    pin:
      number: GPIO13
      inverted: True

    on_press:
        - switch.toggle: relay

I followed the example here https://esphome.io/cookbook/brilliant-mirabella-genio-smart-plugs.html#gosund-sp1 using the GPIO numbers from the link in your first post.

Hm, I get an error for GPI05 can not be resolved for board esp01_1m.

wills106 · April 2, 2020, 9:52am

Sorry typo, it should be “GPIO05”

Will update post.

wills106 · April 3, 2020, 3:38pm

@skycryer

How did you get on with the code change?
Is it functioning how you wanted it to?

skycryer · April 3, 2020, 3:52pm

I still try to get the build back working. I get timeout while building from Plattformio.org, not sure why. Some weeks back it worked without any changes.

I was able to compile your code in the SuperVisor (HASSIO) addon.

But I had to comment some bits out:

Total code now looks like:

  # Lower value gives lower voltage readout
  voltage_div: "955"

@wills106 i was Finale able to compile and test your changes. I am not able to toggle the plug by pressing the button on device or toggle the switch.

skycryer · April 6, 2020, 5:36pm

Ok got it now correct working also with Button press. The problem was I used the wrong config. The Aisirer AWP07L also has V2 config, this config was correct then.

wills106 · April 7, 2020, 3:37am

Glad you got it working.

Saves buying more plugs.
