Units stopped communicating (and preceding weird short cycling behavior) #50

First of all, thank you for creating and maintaining this, it's been really helpful.

Second, this is most likely not a hass-kumo issue, but like others before I'm hoping someone else here might have had similar issues and can help.

I have 3 units with Wifi adapters (and additional wireless sensors) that have been working fine for a bit over a year.

I've seen two issues that I suspect might be connected (based on the temporal proximity):

  1. A couple of days ago (without anything changing to my knowledge), I noticed all 3 units were starting to exhibit a pattern were they'd turn on (heat mode) despite the current temp being above the usual temp they turn on, and turn back off after 5-10 min. This happened about 1-2 times per hour on average. I tried re-pairing the wireless sensor, but that didn't seem to change anything.

  2. Then last night I wanted to use the kumo app to reset/re-add a unit to help with debugging, and noticed that it's showing a connection error (from router to cloud). A little later, and I'm not at a point where none of the units communicate correctly with the app or kumo-hass (or my own python script inspired by kumo-hass). When I try to add a unit as new zone, the app is stuck at "reading unit" or something like that and after several minutes shows a connection error. The wifi unit blinks slowly twice.

I can ping all units from the hass machine. When I used Python to try to connect with a unit manually, I get "_api_error": "device_authentication_error" (which I presume is because the wifi interfaces tried to set themselves up with the cloud server and failed.

I've tried power-cycling and resetting pretty much everything, even using another phone as a hotspot to rule out WiFi/ISP issues.

I'll try Mitsubishi customer service tomorrow morning, but based on past interactions I don't have too much hope. I'd be grateful for any advice anyone can provide.

Thank you!

For posterity, the issue was that the kumocloud servers were down for several days. They seem to be back up now.
