[APP][Pro] EasyLighting - Make smart home easy

I have Homey pre-2019 model and the EasyLightning app installed. The app suddenly stopped working yesterday. I tried to reboot Homey, but it didn’t help.

I have had the app and devices for about a month, and the first problem appeared a week ago. Then reboot helped. Now, it doesn’t help.

When I attempt to control a device, I receive an error message stating, “Device is unreachable.”

All other apps and devices appear to function correctly.

I found this message from the forum https://community.homey.app/t/easylighting-app-stopped-working/135268, which suggests that I am not the only one having problems.

My devices are in difficult-to-access places, so I wouldn’t like to try to remove the app and reconnect them to test if it helps, if I’m unsure.

The devices are:
Sunricher HK-ZD-CCT-A
Sunricher ZG2833K8_EU05
Sunricher ON/OFF
