I bought 6 sonoff devices and I tried upgrading to 3.3.0 on one device. The energy monitor most of the time doesn't work. It's like stuck to 0 Watt or whatever the last number is there. Sometimes it just drops to 0 Watt even when the AC is working.
I'm not upgrading the other devices. How can I revert to previous firmware to fix this?
shit, after 15 hours, stop working again.
Well, yesterday, after update, POW R2 back to normal, sending updated values about power comsume, but today nothing works again. I think the update not solved the issue.
EXACTLY the SAME problem as u said. First i was happy to see that Firmware 3.3.1 will fix all bugs and brings my POW R2 back to perfect condition but its no use.... SONOFF should bring again new firmware 3.3.2 LOL
New firmware 3.3.1 fixing the problem is available :)
