Device status desync (Philips Hue & Sonoff) in Homey app after recent updates?

I won’t go into any further detail about your problem, but it would be important to know how you’ve integrated your devices.

Based on that statement, I’m assuming you’re using a Philips Hue Bridge, right?
If that’s the case, then your home LAN/Wi-Fi network could also be the cause of the problem.

For SONOFF devices, it is essential that you also mention how they are connected to your Homey.
SONOFF Zigbee devices can be connected directly to your Homey. However, it is also possible to pair SONOFF Zigbee and Wi-Fi devices via a SONOFF Bridge using the Homey eWeLink app.
If the SONOFF devices are also connected to your Homey via a bridge, then your home network could also be the cause of the problems.

You can check for yourself in the Homey App Store to see if any of the apps have been updated in the last few days → Apps for Homey Pro | Homey
