I have two of these plugs (possibly 3) that are broken.
One would not turn on the relay. I tried updating the firmware via OTA and got stuck in SAFEBOOT mode. I did a "reset 1" and no change (came back in SAFEBOOT. I did a "reset 2" and it did not come back. Nothing at all. No lights, no access point, no response to ping, no web UI. I tried plugging/unplugging 6-10 times quickly, no change. I tried holding the hardware button down for 30+ seconds and nothing.
The other one I have the relay appears to have stopped working. It would not stay on and kept shutting off. Now I cannot get it to turn the relay on even under just a lightbulb load. Tasmota is working and I can toggle but nothing is happening.
Is there a way to open these devices to inspect or access for direct firmware upgrade? I didn't want to physically break into it, not sure if they are glued or should they pop apart?
Unless someone has other thoughts on how to revive them?
Thank you!
