Almost 2 years on, and I'm wondering if anyone has come accross any other thermostats that do NOT require a cloud connection?

I currently have a CT30, but it's 1/2 brain dead thermostat... You get what you pay for. The entire API is in F, so I need to do F to C conversions everywhere in my HA setup. On thermostat itself, the rounding F to C conversion is flakey. Depending on what the thermostat is doing, fan, heating, cooling, etc it may not let you set it to 20C. (It will skip from 20.5 to 19.5). The API doesn't let you set aux/stage 2 heat mode, you can't set the differential temp when to engage aux. Their is no energy recovery mode for heat pumps.

I 've looked at the Honeywell, Nest, Ecobee... They are all cloud based. Unfortunately my heating/cooling data is not for sale or analysis, so I don't want a cloud service. Venstar has a local API, but it is very limitted and still doesn't have some the features in my rant.
Any other options?
I'm actually pondering if it's worth going back to a wired rs232/485 tstat!
