Once again, my Mark I got messed up, and my first attempt to reload it failed. I wound up zero-filling the whole SD card, then installed my emergency image. I set up the unit again, it upgraded to 20.08.30, if I have understood Mycroft correctly. I find that the OpenHAB skill is now missing from the skill store, which I checked after Mycroft said he couldn’t find that skill to install.
I am still digging around for options, but I was wondering what is going on with the OpenHAB skill. It was really handy to be able to voice-control my lights.
