| Honeywell TCC thermostat | Works | Thermostat control with temperature and humidity sensorsSaved copyI refactored the code: new `TccSensorsAccessory()` function mirroring existing `TccAccessory()` function only fires conditionally if sensors is set to `outside` or `all` because both thermostat and sensors accessories must update when `pollDevices()` fires and both accessories include ThermostatID to link the two to the thermostat off which we are getting outside sensor data, `TccAccessory()` and `TccSensorsAccessory()` now use `getAccessoryByName()` to check if the accessory/services already exist to create/update (rather than `getAccessoryByThermostatID()`) removed `advanced` option from … Excerpt saved from GitHub on 2026-10-22. | PR #91 · 2021-01 |

| Honeywell wifi thermostat (2008 era) | Works | TCC plugin used for Honeywell wifi thermostat via Total Connect ComfortSaved copyDoes it/can it play in the total connect comfort site?

| Honeywell outdoor temperature sensor | Partly works | Outside temperature showed 127.9 when unit has no outdoor sensorSaved copyAnd a little bit more.
