Thank you very much for the explanation. So in this situation, Hunter’s Soil Clik probably comes with a built-in threshold converter.

I agree, the ESP32 would be a tremendous option.

Hi Ray,

This is great! Already looking forward for 2.2.0 with MQTT support 😉

Are these soil sensors an improvement over rain sensors? Are they generally worth it?

The usual suspects are PubSubClient for synchronous and AsyncMqttClient for asynchronous style.

That look like a great start! I would definitely love to see this on the next firmware update 🙂

Having used Home Assistant for a while, I would just keep it very simple: a state subtopic for each station, i.e. opensprinkler/station/4 with the following payload sent with the RETAIN flag:

{
  "state": "on",
  "name": "My First Station",
  "duration": 10,
  "updated_at": 1530394861
}

Then another subtopic for setting station data, i.e. opensprinkler/station/4/set:

{
  "state": "off",
  "name": "New Station Name",
  "ignore_rain": true,
  "sequential": false,
  "enabled": true
}

Main controller settings could be updated using the opensprinkler/set topic, probably on a 2nd phase.
