Improve the precision of the binary_sensor.fan_running depend of the temperature

[Chickenbreast0]

Good morning,

This is less of an issue for me and more of a question regarding the starting temperature of the fan.
Your code shows an active fan from 45°C. In my case, however, the fan switches to active above 43°C and switches off again below 40.5°C. This means that the ICON of the fan is not active, even though it is already running, as I have only reached 45°C a few times so far.

Is it somehow possible to change this in the code so that the value is set as "Fan on" from 43°C?

I will compare the threshold on my side another time and make the value configurable if it's different. At the moment it's hardcoded and cannot be changed easily.

Thanks for your reply.
Addtionally I found out, that your current code works corrcetly, if the inverter temp reaches 45°C. Then it shows, "FAN on" even it is running since 43°C.

The fan of my Soyosource 1200W (Display version + chatty via RS485) turns on at 44.5°C (the display shows ceil(44.5) = 45°C) and off around 40°C (40.4°C).

@Chickenbreast0 Which model do you own?

Mine is a 1000W non-wifi model with display and talkative RS485 Port. Those values above I got from the RS485 Port.

Offtopic reg. the talkative part: I replaced the CPU PCB with a "new" one from Aliexpress for testing purposes. Suddenly it stopped showing me all values. After changing it back, it "spoke" to me again. Therefore I guess the communication thing depends on the CPU Board.
