Mine (attempted to) auto update two days ago, but I just saw Inovelli OTA URL Changes by codyhackw · Pull Request #1159 · zigpy/zigpy · GitHub , which is a change from a few months ago that changed the URL for the Inovelli update JSON. I’m still running HA/ZHA from November 2022, so it’s checking the old URL that has 2.14, rather than the new one that’s only at 2.08.
BTW, I was having trouble getting my switches to update, but got it working by pulling the air gap on about half of my switches and letting it try overnight. I don’t know whether it was reducing the number of switches or just letting it try for several hours (or if both were needed) that ended up working–I still saw failures when only half the switches were on the network, where the switch would show the flashing green progress, then after like 30 minutes, three quick red flashes. It does seem like ZHA should stagger the updates instead of trying to update every switch simultaneously.
In any case, I love the new firmware so far! As I had mentioned in another thread, my main gripe was that even at the lowest dimming level, some of my lights were still fairly bright. Now, those lights are really dim at about 9% and cut off completely at 7 or 8% (so I’ll probably set the minimum dimming parameter now). Thanks to the Inovelli team!
