Dear Terence,

Many thanks for sharing this information. You asked if anyone has an OpenAPI specification for Tado, and I think that there is indeed one written by Dennis Frommknecht on the OpenHAB github on the link below.

https://github.com/openhab/openhab2-addons/blob/master/bundles/org.openhab.binding.tado/src/main/api/tado-api.yaml

I think his specification is not fully complete, and would benefit from being completed with your own knowledge added. For example, I want to add “device:batteryState” to this specification. Any thoughts?
