MQTT HomeAssistant relay control

[aarturoo]

I bought an EMS module from you and connected a WemosD1 S32 and a relay module to it. I added all this to my smart home "HomeAssistant". Unfortunately, I don't see any possibility for mqtt to add control of this relay directly from "HomeAssistant".

configuration.yaml I add this:

mqtt:
switch:
- name: "Piec1"
state_topic: "ems-esp/analogsensor_22"
command_topic: "ems-esp/analogsensor_22/set"
payload_on: "1"
payload_off: "0"

But isn't work.

Is it possible for me to be able to turn the relay on and off from within the smart home?

For connecting a relais, especially the dangerous D1-shields, read: https://bbqkees-electronics.nl/wiki/gateway/using-gateway-gpio.html

Switching a gpio depends on ems-esp-version. You have not added the support-info, so i guess actual:

• add analog output, gpio 22, name piec1
• use command ems-esp/analogsensor/piec1
• or use ems-esp/analogsensor/setvalue with payload id:22 and value:on/off (or 1/0, true/false)

With HA integration i can't help.

Yes, I know. That's why I made my own shield with an optoisolator. In addition, the relay is to switch the voltage-free (signal) contact.

I add analog output GPIO22, name relay.

I add configuration.yaml:
mqtt:
switch:
- name: "Piec1"
state_topic: "ems-esp/analogsensor/relay"
command_topic: "ems-esp/analogsensor/relay/command"
payload_on: "ON"
payload_off: "OFF"

But it doesn't work.

The relay works for me only as I directly control it from the EMS side. Unfortunately with the home assistant after adding the above code and trying to control it, nothing happens.

I use ems-esp32s with firmware version 3.5:

Thx for the support info, you have ha-discovery enabled, so we need to fix this discovery to set the command topic right.
The command topic should be ems-esp/analogsensor/relais
The state-topic ems-esp/analogsensor
and the val_tpl {{value_json['22'].value}} for the nested mqtt (your setting) or for single: {{value_json['relais']}}

[MichaelDvP]

Please check if discovery in https://github.com/MichaelDvP/EMS-ESP32/releases/tag/latest works. (I can not test, i don't use HA).
