Get current temperature? #79

Closed andig closed 2 years ago

andig commented 4 years ago

If the MEL is able to work against a target temperature, it should be able to understand the current room temperature. I'm wondering if that value is available anywhere?

Hi, You can collect the status by subscribe to a MQTT topic, and is called "roomTemperature" The topic is: topic/HVAC_XXX/state The json received: {"roomTemperature":26.5,"temperature":26,"fan":"AUTO","vane":"AUTO","action":"cooling","mode":"cool"}

Great- might be nice to add those to the readme or even expose those JSON values as subtopics to state for easier consumption?

gysmo38 commented 4 years ago

In fact it is already the case you have two topics: settings and state

I don't think so- or its not documented (sorry, still haven't installed my adapter). I'm looking for the current temperature, something like

topic/HVAC_XXX/state/temperature

That doesn't seem to exist yet?

@adamderuwe I may not have made this clear enough. What I meant is

HVAC_master/state/roomTemperature
HVAC_master/state/temperature
HVAC_master/state/fan

etc. That way one could use the state without further need for decoding the json!

It seems fairly common to arrange the state the way the library implements and MQTT Explorer is able to parse out the JSON. HomeAssistant also is working fine with the existing code.

I have seen another MQTT "standard" proposed that arranges them the way you're looking for at https://homieiot.github.io/tools/.

Arranged something along the lines of...

homie/mitsubishi2MQTT/$homie 4.0 homie/mitsubishi2MQTT/$name My device homie/mitsubishi2MQTT/$state ready homie/mitsubishi2MQTT/$extensions homie/mitsubishi2MQTT/$nodes mythermostat
