Which exact heatpump do you have? If you have an external and internal unit, both model versions are important.

[alexswart]

It is an ferroli omnia hybride with an 6kw outdoor unit R410 When i see the register adresses they are all the same for all the midea units. Some functions are working, i can change the outlet water temperaturen setpoint

I can’t find the modbus overview for a hybrid model at the moment. The model you gave is to broad btw, the exact model, for example “ferroli omnia s hybrid c 3.2” is important to find the right info.

But in general, it seems that register 100 (0x64) is not supported on your device. Remove that one from the list and then try again. Hopefully that is the only register that’s missing.

Please let me know the outcome, including your exact (!) model, so that we can help others as well.

That is strenge, i have check my old integration rs485-> usb-> nonered and that works also with adress 100 and shows the frequency of the compressor, i want to check my serial-> 485 board maybe that is the problem

Hi @alexswart , I am having similar problems with a Kosner unit (Midea clone), and I have a rs485 --> serial TTL converter. Did you find any solution for the "Component modbus_controller took a long time for an operation " messages?

Thank you!

[alexswart]

@buitre-buitaker still no solution for this, i have also try diferent esp board en diferent ttl converters but all give the same error

Component modbus_controller took a long time for an operation

This message is an informational message from ESPHome and not an error message. It prefers to handle operations within the mentioned time, but that's unfortunately not always possible.

You can filter out the component took a long time message by using this code
