[revk]

If you know it is definitely S21 you can set nox50a, and the settings kit to invert tx and rx.

That will simplify the logs at least, as it tries many combinations.

It may then be worth power cycling the whole lot (air con too).

Then get some more logs from MQTT.

[seafurymike]

wow. played with the protocol settings and it connected. it shows

Faikin-S3-MINI-N4-R2: ebf3c2b 2024-09-26T14:35:29 Altherma_S

so its no s21 or Nox50a??

Now, its connected but i can’t turn the unit on via the web if i have MQTT connected?

[revk]

I don't think Atherma allows control, just reporting of settings.

I'll have another look, but it is not S21 protocol.

[seafurymike]

With debug on i don’t see anything come in.
With dump enabled I see the following only.

Is there anything specific I should enable to derive the info needed?

[seafurymike]

This state info is presented at the start of listening

[revk]

I am not sure how far Altherma development got, I thought we had basic state info. Select latest beta, if you have not already.

[seafurymike]

Ok will try the beta.

[seafurymike]

I upgraded to the beta version and tried to send an “on command” to the system (so hard to work out how to do this, could you please put examples in the manual for people to reference and make the link for the command easy to identify the options you can use)

So I sent the following to,power on the unit:

command/FaikinBroom/on

This is the error:

then I tried to send a command with json format, I am not sure this is right how I formatted it, but got the following

[revk]

Yeh I don't think the interface for Atherma has a means to send any controls.

[seafurymike]

I just want power on. Shame

[revk]

I know there are some other people who have been working on this, but I think we concluded there is no "control" in the protocol even. If someone works it out I'll add to the code.

[andi-christ]

@revk FYI I've had a batch manufactured and am distributing them in Australia. This is one of mine. @seafurymike send it back and I'll pass it on to someone else. Pls add your model to the wiki and indicate it's not compatible.
