Adding MYQ-HY09RF? #204

Closed Stoatwblr closed 8 months ago

Stoatwblr commented 1 year ago

I've picked up one of these beasties off Aliexpress and flashed it with Wthermostat

It seems to work ok (and be using the same standardised commandset) however temperatures are not being recorded so it's obviously just slightly different enough to trip things up

What information do you need?

Hopefully this helps

Hi,

Is there any chance of implementing this type of thermostat in the near future? I bought this one because I needed a battery-powered version.

The firmware uploads okay, but the log is full of MCU warnings. On the info page, I noticed that the temperatures are not being read correctly from the MCU. For example, a set temperature of 20 degrees is displayed as 100.

If this information helps:

I found another similar topic on the klausahrenberg/WThermostatBeca repository: https://github.com/klausahrenberg/WThermostatBeca/issues/84. I tried their firmware, and when I choose the Minco Heat MK70GB-H thermostat, the temperatures display correctly, but there are still a lot of errors.

Is there any possibility of implementing this thermostat in your code?

Thank you!

Long time, but I have a dpid set for this (also posted to Klaus git https://github.com/klausahrenberg/ )

This appears to be common across Hysen thermostats (Hy02/Hy08 in addition to Hy09)

These DPids are all emitted every couple of minutes (settable in the B menu on the panel - B5 0-30min, B6 3-30 seconds - default is 20 mins, DON'T change it if using batteries in the panel or they will drain quickly)

OR whenever the clock is updated by Homeassistant, or if the panel mode/temperature, etc is changed

There's what appears to be a heartbeat as well, this is using type 1C clock reports (I'm ignoring it)

Temperatures can be set arbitrarily high/low and the protection toggled

(**) Detected and automatically set (readonly) on HY09, programmable on other models 2: DPid 116 is assumed from HY02 decoding (see next comment). It's not adjustable if no external sensor circuitry is installed (ie: could be used to interlock internal/external sensor viewability)

The original app has commands to adjust panel display contrast/viewing angle, which I haven't yet managed to replicate

The original app also reported low battery on the remote panel but (so far) I haven't worked out where this is reported I assumed it would be one of the unknown DPids but with the low battery icon flashing on the panel none of these have altered
