Danfoss Ally and Z2M

[MSL-DA]

Danfoss Ally and Z2M have been a disaster, and I’ve been well on my way to finding another solution than Danfoss.

In Danfoss’s own documentation, it is stated that the algorithm_scale_factor (0x4020) is = 1 by default. That is simply not the case.

I have found it more than difficult to achieve the desired temperature, and I had to give up on schedule_with_preheat because I never reached the desired temperature.

I’ve had my thermostats in Z2M for a year, and then I sent {"algorithm_scale_factor": 1} to all thermostats and voilà, all thermostats started responding as expected.
