sonoff RF realy toggling continously for no reason and on every remote button press

[hjgode]

I compiled sonoff 2.0.7 and put it on four sonoff, one of these is a sonoff RF with a 433MHz remote.

When I press the remote button to switch the relay, the relay starts toggling and will not stop except when I press the button on the remote in a specific sequence. Toggling the relay via MQTT works ok and does not start toggling. I first had a wrong definition in FHEM server and two sonoff devices where subscribed to the same topic. But even after correcting this, the relay now starts toggling for ever when I use the button on the remote to switch the relay.

The relay will also start toggling for ever when the button on the sonoff is used to switch the relay.

The sonoff RF has been modified as the button is normall only connected to the RF part and so it was not possible to enter flash mode. R9 is removed and R21 has been soldered (both are just 0Ohm).

Can you help? or do I need to reverse the R9/R21 swap?

Hi and sorry for any confusion

I did not only swap R9/R21 but had both 0Ohm 'resistors' in place (just solder bridge). With that, sonoff RF will start to toggle contiously on first relay switch.

Removing R21 braught the device back to 'standard' sonoff RF. Now it cannot be flashed by FTDI with pressing the button during power connect, but will switch the relay correctly either by the button, the remote or MQTT. Flashing is still possible using the web interface or MQTT.

Thanks for the great efforts on this software.
