RF (433mhz) not working?

If you kept data, why would you need to reconnect all devices? Or did you mean only RF devices?

It’s only the RF devices that will not connect. I have removed them all from homey but cannot reconnect them.

Sorry, I was responding to another poster that did a full reset. If you do a full reset not keeping data, you would have to do a backup restore. Keeping data is the same, even slightly better.

Backup restorr was not working in my case
