2 people have this question

hi guys, with the latest version of firmware 3.3.0, my sonoff 4ch pro r2, they no longer work with Alexa, in Lan switch mode it does not display the channel names and does not exit this mode. can you tell me a way to downgrade firmware to version 2.7.1? Best regards Ros
Hi Brad, I had same issue and just replaced them with the ifan03. Everything about the ifan02 sucked (random wifi dissconnections, beeping, remote batteries died once a month). The new ifan03's actually work as advertised (for what it's worth). Key lesson I've learned is do not update unless you absolutely have to! If I wasn't 30'ish Sonoff devices committed, I'd ditch the lot. But hindsights a beautiful thing.

Why don't you try the new firmware before downloading it? Power R2 which turned off when it drops below 5 W, does not shut down after the firmware update.

Can anyone confirm that this fixes T1 3C random beeping, turning on/off (wifi drop outs)? I don't trust these updates having been burnt by the last one...

since upgrade to 3.3 on my sonoff rf, the Power ON schedules are not working if the sonoff have no internet connection.

As my wifi is turned of at night using a sonoff... it never comes back on

3.3.0 did not solve any of problems on G1 Inching/Self locking device. Still losing the connection and pulsing the relay after power lost.

I miss the old 2.6.0 or 2.6.1
