| REST API | Works Local | Complete local API; no internet needed; scripts run reliably, not 100% per one userSaved copyRadio thermostat has a pretty complete API. I've got two-- the CT-80 and -100 I believe. Neither can see the internet, they integrate with HA well, and I have some pretty complicated scripts updating them that have never given me any trouble.
