I have heard that Homey can have issue with a dual band SSID. I have always separated mine as I have a few other devices that just don’t work in dual mode.
If Homeys network is flaky then it’s possible that the app was getting a lot of connection timeouts and again I have heard that can cause memory issues with the network stack.
I have nearly finished with the SDK3 rewrite so I will hopefully publish a new test version today.
