433Mhz not responding after reboot

After a Homey reboot all 433Mhz stopt working. Last reboot, about one month ago, the devices also stopped working but after an hour it was up and running again. No problems since than, but after todays reboot (first since the reboot last month) the devices aren’t working even after 1,5 hour. For the 433Mhz part I only have one curtain (Somfy) and one light switch (KAKU).
When I send a command from the device self in Homey (so without a flow), I get a network timeout after 30s. Looks like the hardware layer that handles the 433Mhz part isn’t responding to the request.
Has anyone a solution or the same problem?

433 seems instable here too…
Never had problems before… :frowning:

Same here. I had to reboot 2 weeks ago and Somfy RTS was broken. I tried to re-pair but without luck. I involved support which pointed to MQTT probably taking too much ressources. But after a day and without any change, it magically worked again. A week later I had a power outage. After rebooting Homey, RTS was broken again. I waited patiently for 1,5 days and guess what…? The magic happened again. But it’s scary… and feels very unreliable.

After aome more investigating, it now seems that especially my KAKU (COCO) remote seem to bee unreliable. They do switch all the devices which are directly connected to the remote, just not the ones that are operated by Homey flows…
When I trigger these flows through the Himey app the respond instantly.

Sounds strange, not something in your flows?

So I need to wait a bit longer I guess (hope).

Probably not.
As said; when I start the same flow manually from within Homey it functions flawlessly

Have you tried pulling the plug for at least 15 minutes?

Same problem here with all 433 devices(telldus and nexa)
Went to developer.athom.com-tools-signals
Record 433 and pressed on a 433 remote controller.
After a few seconds all 433 devices went crazy and then it works again.
But 12 hours later same problem apaired again…

Now exactly 24 hours later 433Mhz is working again… What I did noticed is the load on Homey, within the first +/- 24 hours it was above 200% (didn’t even know this was possible). Now it’s below 100, and everything is working as before the reboot.

I have the same problem.
