I 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 …

Does it/can it play in the total connect comfort site? There's the homebridge tcc plugin that I use for my Honeywell wifi thermostat, though my unit is from circa 2008.

Honeywell outdoor temperature sensorPartly worksOutside temperature showed 127.9 when unit has no outdoor sensor

And a little bit more. Do you have an actual Honeywell outdoor temperature sensor ? I was looking at the data, and I'm not seeing it transmitting anything The code is looking at the data in the UI blocks ie [code] And expects the outdoor temperature to be in a field called `OutdoorTemp` But I don't see it....The code does not print unchanged data, so it may only appear, but it is surprising to be missing if you have the sensor
