Shelly 1 "device not available"

Dear all,

I have linked the “Shelly 1” module to Homey. The moment I reset/restart Homey, it is listed and working properly. After some time, sometimes a few minutes and sometimes a few hours, the module becomes unreachable and has "device not available: request to http:///status failed, reason: connect ETIMEOUT . It no longer connects itself. Wifi is ok / -68 RSSI

After resetting Homey, it is there again and works fine again. What could be wrong?

One possibility is Homey’s unstable networking.
