This is an app for Homey that works with the Pi Relay Controller Server over gRPC calls.
Install from the command line using homey app install.
The server is discovered using MDNS. For networks or subnets where MDNS isn't supported the app can be installed on the Homey in the normal way and the IP address and port number of the server manually entered in the app's settings; where this is present it will be used in preference to the MDNS lookup.
Each relay can be renamed in the device's settings as normally and those changes will be written to the server and stored in the database, which allows renames and state changes to persist over reinstallations of the Homey client app.
