Seems like 433 is failing on my Homey PRO 2019. Little by little, all my 433 remotes have stopped working. And today, my wired 433 switches have begun showing issues. The closest one, a NEXA CMR-101, is located 0.5M from the homey. It will no longer work. I have tried removing and re-pairing it. It…

I’m no longer using any 433 remotes. All have been replaced with Zigbee devices, given the previous 433 issues. Homey has been power cycled numerous times. I’ve even turned off the breakers in my fuse panel, to power off the 433 switches/relays. I live on a farm. No neighbours to worry about.

I have pulled the plug several times. I’ve also tried moving the Homey closer to the various devices. Everything worked like a dream in the beginning, which is about a year ago. Now I have nothing but headaches. Seems like the on/off switches on 433 are still hanging on by a thread, and the CMR-101 …

Marius, did you buy a thermometer or other 433 type of device? And what about switching a receiver direct with a remote controller? Does that work without any problem? To me it looks like a device that constantly jams the 433 band.

In my setup, I have 2x LCMR-1000 (wired relay/switches), 3x CMR-101 (wired dimmers), 1xLGDR-3500 (outdoor smart plug), as well as 6x MYC-2300 (smart plugs). None of these, as you can probably tell broadcast continuous data. I have gotten rid of all the remotes, and I have removed the battery from a…

Have you tried a new Power Supply (with enough power)?
