Number of compressor starts and keeping a stable temp while cooling. Setting recommendations?

[zaubara]

I'm using 4x Faikin in my 4-way Perfera multisplit.
While I'm waiting for the BLE sensors to arrive, I figured out that it's already possible to connect to MQTT sensors, which is amazing. I already have set up some Zigbee sensors around the rooms that report quite good values.

Ever since then I've been playing around with the settings - trying to get it to maintain a stable temperature with the Faikin Auto mode. The built-in temperature sensors seem to be quite far off the real room temperature.
Using the default settings, the AC is set 6° higher or lower than the current temperature (depending on other settings), but this makes the AC go wild - having to reach quite a big difference. When the temperature is reached, Faikin then - in the perspective of the AC - "suddenly" increases the requested temp by 12 degrees, stopping the whole compressor when no other inside unit requests cooling.
This results in repeated cycles, turning on for a few minutes at full (?) power and then turning off completely.

From my understanding, it should be one's goal to keep the compressor running at a low setting with as little restarts as possible.

With my current settings, it keeps the requested temps quite well, but the compressor restarts way too often for my taste:

I also don't quite understand why it starts and stops when it does, after reading the docs a few times. I have set the thermostat mode on, autot 26.0, autor 0.5, coolover 1, coolback 4, temptrack off, tempadjust 1. These settings I played with. thermref 50, switchtemp 0.5, pushtemp 0.1, unchanged.
In thermostat mode, I'd expect it to turn on when reaching 26.5 (26 seems to be the moment it turns on) and turn off when it's at or below 25.5 -- it seems to stop earlier.

Do you guys have any recommendations how I can get it smoother, without having it turn off and on so often?
How many restarts per hour or per day are OK?
Thank you!

The BLE Sensors arrived, and this has improved results by a lot - my zigbee sensors probably didn’t report often enough?
I also set coolover to 0, and with demand set to 40% the temps are held quite well now, although I’m not sure if changing demand actually changes anything.

The starting and stopping early in thermostat mode is caused by the predictive part of auto-mode.

faikin tries to predict the “next” temperature by monitoring the slope of past measurement. Eg. If it is 26 degrees but temperature has been steadily rising (or there was a sudden jump in temperature), it anticipates that 26.5 will be reached within “tpredictt” and starts cooling.

you can disable the predictive logic by setting tpredictt to 0 in the settings

@zaubara I am kind of in the same shoes (and with Perferas too). Would you mind to share your findings and settings since you posted?
