I have 3 UNICAL air conditioners (rebranded midea), for all of them I receive this error randomly.

For none of the 3 I receive the energy consumption (via midea app for 1 it worked).

For 2 air conditioners I cannot set the ECO preset.

The loop is about 50-60ms.

What data can be used to help the analysis?
