For the last couple of months, thermostat actions performed via the HomeKit UX no longer seem to bridge properly to Indigo.. I'm using the Unistat plugin 'Device Unistat' model as a virtual thermostat in order to turn on space heaters/ceiling fans. From my observations, if you change the state via Indigo it is properly updated on the HomeKit UX. Indigo and the Unistat plugin seem to work fine together. However if make changes via Homekit UX such as Thermostat 'Mode' or 'Setpoints', these don't seem to properly relayed back to Indigo.
AFAIK this was working properly until about November. I realize there are several touchpoints here - HomeKit / Unistat Plugin / Homekitlink Siri plugin / Indigo. Anyhow, thought I'd post here in case others have observed the issue..
BTW - i did a quick test with the Ecobee Indigo plugin as a thermostat.. All seems to be working fine with that one. However, from what I see the Unistat plugin hasn't changed since well before my issue (7/17/2022)
Any tips appreciated.
