Hi all,
on yesterdays sesson I observed a strange behaviour (Stellarmate 1.7.1):

I started my session, everything works fine. So I switched on cooling of my QHY268C down to -10°C. Cooler goes up to 100%, looked fine. But then I saw, that the temperature tryed to go UP to +10°C with always cooler at 100%! I changed target temperature to -8°C (and yes it was set to MINUS 10°C before) but still the same 100% cooler and about +10°C. I tried cooler on/off, but nothing changed. I disconnected the camera from INDI and reconnect: just the same behaviour. I had to physically disconnect the camera from the setup (remove voltage supply), afterwards it worked: -10°C at roughly 40% cooling power.
Now I remembering, that this was at least once the case after updating to 3.5.9, in the older versions I never saw this strange behaviour. I thought there was just a mistake in + and - but also at that time I was wondering that the cooler was at 100%!

Unfortunately I had the protocols not activated.

I have observed the same thing with a QHY600 running ekos/kstars on Ubuntu Linux. Restarting the driver from the control panel usually fixes it.

Hi Thomas, good to hear not to be the only one with the issue.

just to be sure: you mean this button:

Yes, that’s it.
