How to control HestiaPi via MQTT injection?

jizhoul · January 19, 2023, 4:56am

Hello,
I am interested controling HestiaPi via MQTT injection.
For example:

inject “ON” to “hestia/local/cmnd/heatingmode”
inject 72 to “hestia/local/mintempsetpoint”

I got it working partially, that it changes the mode and set temperature on the LCD.
But, on OpenHab the temperature and mode is still the same. And the relay wasn’t turn on either.

Could anyone help me properly control HestiaPi via MQTT injection?

Thanks

Best way to explore this yourself is to use the LCD and monitor all MQTT communication. LCD script is in fact communicating with MQTT with OpenHab even though they are sitting next to each other
Have a look in the LCD source code too:

HestiaPi/hestia-touch-one-ui/blob/46e68431dcff1adcb483286b4234606c0626bf86/src/plugins/store.js#L105


      
              incrementTargetValue,
              selectMode,
              selectPowerSetting,
              toggleInfoScreen
            }
          })
          
          
function mqttClientPlugin(store) {
            store.client = client
          
          
  const messageCallbacks = {
              //
              // Mode-setting topics
              //
              'hestia/local/cmnd/coolingmode': updateMode(store.state, 'cool'),
              'hestia/local/cmnd/fanmode': updateMode(store.state, 'fan'),
              'hestia/local/cmnd/heatingmode': updateMode(store.state, 'heat'),
              'hestia/local/cmnd/hotwatermode': updateMode(store.state, 'hotwater'),
              'hestia/local/cmnd/humiditymode': updateMode(store.state, 'humidity'),
              //
              // Power-setting topics

Thanks! It turns out I changed the wrong MQTT topics.
Instead they should be:
“hestia/local/cmnd/setmintempsetpoint”
“hestia/local/cmnd/setmaxtempsetpoint”
“hestia/local/stat/heatingmode”
“hestia/local/stat/coolingmode”

Very Nice!
