STUCK: Help needed with ESPhome scripting refinement for fireplace automation

ESPHome
1

Hi there. I have build a simple script for controlling my Mertik Maxitrol GV60 controller for fireplace. I have studied the fireplace manual for a long time and was able to find out which circuit must be closed for certain functionality for the wall switch connection. I connected a 4-way relay to it with an ESP32. It’s working fine but I would like to refine my script to a more ‘professional’ version with some additional checks. I read alot on the esphome but it’s beyond my programming knowledge.

What I just can’t manage is the following:

  • I would like have a status sensor with an entry of the last chosen platform name turn_on_action
    This way I can read the current status of the fireplace in Home Assistant.

  • Because the relay’s needed to be inverted (otherwise they are all on by default) the status does not want to change to on. I use lambda for this where I look at the status of 1 switch ID. But the way I’ve done it now, the lambda IF states are not unique. I would like to make an IF statement where at least 2 id’s must match before a true can be given.

It’s my first code in esphome so if you guys can help me? That would be fantastic

@ottovw can you please share how you have connected it to your panel
do you have setup 4 switches?\

Create a text sensor

# Example configuration entry
text_sensor:
  - platform: template
    name: "Template Text Sensor"
    id: template_text

Then update it’s status in each automation

# in some trigger
on_...:
  - text_sensor.template.publish:
      id: template_text
      state: "Hello World"
