I’m getting tired of having to download an app just to set up a device. Ive been trying to get only ZigBee devices since most are plug-and-play but theres still some that require the whole app and registration dance.
I recall on the hass.io website being able to search integrations by communication protocol (in my case local polling/local push) but I can’t seem to find it anymore.
Yeah wireshark would be my first bet. All you are really looking for is a ntp server that it’s trying to reach on udp port 123. If its not using ntp then it gets waaaay harder as they have rolled time sync into their own Api
