I tried to update my hass.io-system from ResinOS to the new HassOS based version. Unfortunatelly there is a major issue with HassOS:
After the migration (it worked for a day) there are issues with under voltage which leads to hass.io not fully starting (ssh works, UI doesn’t). The same configuration works quite well with ResinOS though. Luckily I put HassOS on a new SD-Card so I was able to switch back easily.
I tried several USB wires and several power plugs (even some pretty strong with more then 2.5A): Whenever I try to run HassOS it fails, but ResinOS-Version is working fine. Again: Same configuration. SD-Card is fine, too.
Most USB adapters are for charging and have crappy filtering and when current load gets high the voltage sags or gets a lot of ripple. This is ok for charging as most devices will ignore it and you just get longer charging time
But to power a device like a rPI you need something that can supply the current at stable voltage. I’ve found (as have many reports and tests) that the Apple 12W adapters do a really good job here. When I ran a rPI I tried many adapters with problems and switched to an Apple one and no issues. Even though technically rated for lower power…
Well I have no intention to use a 1kW power supply for my raspberry pi
I tried several quite solid supplies but whenever I use ethernet on hassos, home assistant won’t start (but add-ons are running and I can SSH into the machine).
Question is, what’s wrong with HassOS as it’s running perfectly on the resinOS based HassIO?
For me it seems to be a badly optimized OS that needs some tweaks before going into production.
