My initial thought was I can just call a REST API with a token and message and it would just show it but it doesn’t seem to be that easy. I’m a developer so I should be able to piece this together but I was curious if anyone had any suggestions. Thanks!
You’ll need a way to generate a webp or gif image and then push to the tidbyt api via https. If you have access to linux vps or container somewhere then you can host a little service that accepts your alert string, converts to an image (eg with pixlet) then pushes to the tidbyt via tidbyt’s API.
If you can generate a gif within the homeyscript environment then you might be able to do everything inside the Homey device (which would be awesome). Seems it might be possible to run a docker container within homey but I have no idea about that. It does looks like a pretty powerful hub.
