Problems controlling a Mag Fi heatpump

[YOYONL89]

Hello All,

I just moved from the local tuya to the tuya local integration in the hope of getting a issue with a Mag Fi heatpump to be resolved.
Unfortunally the problem is also present in this integration.

Let me explain:
I have a Mag Fi heatpump for my hottub and i used to control it up to last year summer through the local tuya integration.
Due to some private circumstances the hottub hasnt been setup until now, the problem is i can see data comming from it, like a change in mode or change in temperature but i cant send a temperature or turn it on or off.

The fact that i once was able to control the Mag Fi through local tuya makes me believe it should be working but either something has changed from wich it does no longer work or something has changed on my end but im a bit lost in where to search for it.

Maybe anyone here has an idea.
i will add a debug logging below

For the record:

• The old tuya has been disabled;
• There is no app on one of our phones at home;
• One thing that might be of influence is that the heatpump is on an IoT VLAN with a Pi-hole above it, this setup used to work without any problems though;

Hope anyone can shine a bit of light on it.

What is the protocol version?

Hi Jason, I added it via the auto setting and it came back with v3.3. Tried some other versions aswell but that made it worse or wouldnt connect at all. So i set it manual to v3.3 Op zo 5 jul 2026, 00:46 schreef Jason Rumney ***@***.***>:
