Unable to Control Tado X Theromstats Via Matter Docker Container

[Pembrae]

The problem

I have successfully added my Tado Wireless X Thermostats, TRVs and a Thermostat, to my Matter integration running as a Docker container. The devices were first added to the Tado app and then added to Home Assistant Matter integration using the code provided from within the Tado app.
On first glance they all appear to be working and sensor data is being correctly displayed. The problem I have is when I try to change the set temperature from within Home Assistant. The Temperature will change but will go to some other temperature, quite often 5 degrees C.
I know the Matter Docker Sever comes with warnings and so before I spend hours try to solve this problem and wanted to first check if anyone knows if this is likely to be a fundamental problem using the Matter Docker approach and hence to not bother. I'm by no means an expert in Home Assistant or Linux but happy to have a go solving it as it seems so tantalisingly close to working.

Problem seems to have suddenly gone away so closing issue. Don't believe I made any changes other than enable debug logging, so I could attach log files to this issue, and it started working OK. Haver disabled debug logging and it is still working so will close this issue and hope it doesn't come back, fingers crossed.
