Question to MQTT Input Rules

---

Hey there,
I try to implement a rule that changes the input value of the mqtt input device when a dummy heating thermostat temperature changes.

This here works (but is the other way round):
“rule”: “when $homematicmqttthermoinput.input changes then set temp of homematic-thermo-set to $homematicmqttthermoinput.input”

If I change it to this, I get an error:
“rule”: “when $homematic-thermo-set.temperatureSetpoint changes then set input of homematicmqttthermoinput to $homematic-thermo-set.TemperatureSetpoint”

Any ideas how to do this?

Regards

Two times changes?

Oh, actually this is definitely wrong, but just happened when I copied the code. In. Pimatic I have it just once. Still doesn’t work.

I´m not sure if you can set a variable to an input device…
What does the error-message say?

2018-11-20 07:23:17error [pimatic]: Could not parse rule “when $homematic-thermo-set.temperatureSetpoint changes then set input of homematicmqttthermoinput to $homematic-thermo-set.TemperatureSetpoint”: Could not find an provider that provides the next action of “set input of homematicmqttthermoinput to $homematic-thermo-set.TemperatureSetpoint”.

@flybysun said in Question to MQTT Input Rules:

$homematicmqttthermoinput.input

change input on change? This rule is useless… If the variable get an update, it changes automatically…

Otherwise:

then set temp of yourdevice to $homematicmqttthermoinput.input

The problem is that the MQTT-Input-Device doesn’t act as a heating thermostat. Shure I can increase and decrease, but I’m missing the radio buttons as in the heating thermostat. All I want is to place the dummy-heating thermostat and whenever I change the temperature I update the value to the MQTT-Input Device (which doesn’t have to be visible at all)

I change one Input (dummy heating thermostat) and copy this input to another input (mqtt input device)

I don´t understand why you want to use the mqqt input. It´s not made for this.
If you just want to publish a mqtt-message use:
publish mqtt message "$homematic-thermo-set.TemperatureSetpoint" on topic "YOURTOPIC"

It would help more that you tell us which device you have and where your data came from and what you really do with device…

Is that true that your increase decrease temp on your device directly and you want to update you temp in dummy device?

Did Pimatic doesn’t support you thermostat nativ?

publish mqtt message “$homematic-thermo-set.TemperatureSetpoint” on topic “YOURTOPIC”

This is what I’ve been looking for! Sorry it was a bit hard for me to explain. Thank you for the help, I didn’t know that I can implement puplish mqtt meassage as a rule. I want to tell you what I’m doing:

For my home automation I’m publishing/subscribing everything to mqtt. Where everything means:

• 433MHz switches -> Arduino /w Ethernet Shield and 433Mhz Transmitter listens (subscribed) to mqtt broker
• MySensor Nodes -> Arduino /w Ethernet Shield and NRF24L01 Transmitter write (puplish) to mqtt broker
• HomeMatic Components -> HM-MOD-RPI-PCB on RaspberryPi controlled by homegear via mqtt broker

I wanted to puplish to the “set” topic on the id/channels of the homegear to control my HomeMatic Heating thermostats. What I was missing was the bridge between the dummy-heating-thermostat and the mqtt input device.

But now everything works fine, thanks again!
