10 months ago I had the same problem. I didn't persist as long as you did (because I had the benefit of your post), however once I flashed the MHI-AC-Ctrl firmware it worked right away. I keep everything up to date so it was the latest version of esphome.
Something I was wondering- could the debug messages that have been added regarding timing be causing timing issues?
I have five units. I will try to get the model numbers. The three most modern units I have had a chance to install the modules on- the other two need to wait a couple of days as it's inconvenient to get to them. Out of the five I have four different models!

Hello,
Two days ago I installed my hardware in the AC unit which is a SRK20ZM-S and I uploaded the MHI-AC-Ctrl-ESPHome software on the ESP8266 which is a D1 Mini. Unfortunately I couldn't get it to work. All my sensors gave unknown values and also I didn't get the current temperature value or couldn't change HVAC modes.
Below is the output of the console when the MHI-AC-Ctrl-ESPHome software is active.

And then it just keeps coming up with '[W][mhi_ac_ctrl:139]: mhi_ac_ctrl_core.loop error: -2'
I also got a warning when compiling. But compiling went fine. See the warning below.

I seem to get data on the sensors and can also set the modes and can turn on and off the AC from MQTT. Below is the output from the console when the MHI-AC-Ctrl software is active.

What I have done so far is use different ESPHome versions. The versions I have used so far are 2023.2.0, 2023.4.4 and the latest. I have also used the MHI-AC-Ctrl-core.cpp and MHI-AC-Ctrl-core.h from the MHI-AC-Ctrl which was working for me. But nothing did the trick thus far.
One strange thing I saw from Home Assistant is that after about an hour of being connected some sensor are filled. The current temperature seems to be 19 degrees and does not change over a full night. Also the error code sensor got a value of 1.
