mhi_ac_ctrl_core.loop error: -4

[JunghaJungha]

Hi, I just installed this device, I have no airco readings. The Wemos d1 is connected to HA (all diagnostic values are there).

In the esphome log it continuously shows: mhi_ac_ctrl_core.loop error: -4

Any clue?

Thanks, Koen

I also saw mhi_ac_ctrl_core.loop error: -2 and mhi_ac_ctrl_core.loop error: -1 in the log as well.

Any updates?

I have the same error

[00:07:54][W][mhi_ac_ctrl:077]: mhi_ac_ctrl_core.loop error: -4

Would be great is this can be fixed. I have 4 working AC units now, flashed with older version op ESPhome, but can get a new unit connected now.

Let me know if I can test something

Hi all,

I fully reassembled the hardware and now it works. No more loop errors!

The hardware was the problem for me also!

The hardware was the problem for me also!

What was causing problems? All my 7 devices are reporting loop error: -2

for me it is solved when i plugged it into my AC. When i powered it via micro usb it was giving me error: -4

I'm getting this error on all 3 of my devices. Anyone else with the latest version?

mhi_ac_ctrl_core.loop error: -4 - was for me missing clk connection ; Hardware: D1 Mini and own PCB now loop error -1 , But on / off AC works I think -1 is Timing Problem -

Seems like this is hardware related, if there are issues you think can be solved in software please reopen
