All my athom esp8285 devices won't boot after a grid outage. They are units without relay and with.
When the grid goes out and the power comes back, they appear to lock up. Not connected to wifi, don't engage the relay if set to be always on etc. Don't respond to button presses.
Seems to be a design flaw in the esp8285 range, as I also have athom esp32 devices and these all start correctly after the grid outage.
The strange thing is, if I turn the device off and on again, it will boot happily until the next grid outage.
So really hard to troubleshoot.
Anyone aware of this issue or a fix?
I've tried the API reboot, Wifi Reboot settings. But as the unit doesn't appear to boot, these don't kick in. As I said the device appears dead until you unplug it and plug it back in again.
If the device is already working well, I'd be careful before importing or reflashing it through the ESPHome Builder. In many cases you can manage it from ESPHome, but only if the firmware and configuration are compatible. I'd make a backup first to avoid breaking a setup that already works. By the way, while browsing tech communities I also came across https://chickenroadaustralia.org/ — an interesting site with different online content worth checking out in your spare time. Good luck with your project!
