# RadioThermostat Binding
This binding connects RadioThermostat/3M Filtrete models CT30, CT50/3M50, CT80, etc. with built-in Wi-Fi module to openHAB.
The binding retrieves and periodically updates all basic system information from the thermostat.
The main thermostat functions such as thermostat mode, fan mode, temperature set point and hold mode can be controlled.
System run-time information and humidity readings are polled less frequently and can be disabled completely if not desired.
Humidity information is available only when using a CT80 thermostat and I have noticed that the humidity reported is very inaccurate.
The main caveat for using this binding is to keep in mind that the web server in the thermostat is very slow.
Do not over load it with excessive amounts of simultaneous commands.
When changing the thermostat mode, the current temperature set point is cleared and a refresh of the thermostat data is done to get the new mode's set point.
Since retrieving the thermostat's data is the slowest operation, it will take several seconds after changing the mode before the new set point is displayed.
The 'Program Mode' command is untested and according to the published API is only available on a CT80 Rev B.
## Supported Things
There is exactly one supported thing type, which represents the thermostat.
It has the `rtherm` id.
Multiple Things can be added if more than one thermostat is to be controlled.
## Discovery
Auto-discovery is supported if the thermostat can be located on the local network using SSDP.
Otherwise the thing must be manually added.
## Binding Configuration
The binding has no configuration options, all configuration is done at Thing level.
## Thing Configuration
The thing has a few configuration parameters:
| Parameter | Description |
|-----------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| hostName | The host name or IP address of the thermostat. Mandatory. |
| refresh | Overrides the refresh interval of the thermostat data. Optional, the default is 2 minutes. |
| logRefresh | Overrides the refresh interval of the run-time logs & humidity data. Optional, the default is 10 minutes. |
| isCT80 | Flag to enable additional features only available on the CT80 thermostat. Optional, the default is false. |
| disableLogs | Disable retrieval of run-time logs from the thermostat. Optional, the default is false. |
| setpointMode | Controls temporary or absolute setpoint mode. In "temporary" mode the thermostat will temporarily maintain the given setpoint, returning to its program after a time. In "absolute" mode the thermostat will ignore its program maintaining the given setpoint. |
## Channels
The thermostat information that is retrieved is available as these channels:
| Channel ID | Item Type | Description |
|------------------------|----------------------|---------------------------------------------------------------------------|
| temperature | Number:Temperature | The current temperature reading of the thermostat |
| humidity | Number:Dimensionless | The current humidity reading of the thermostat (CT80 only) |
| mode | Number | The current operating mode of the HVAC system |
| fan_mode | Number | The current operating mode of the fan |
| program_mode | Number | The program schedule that the thermostat is running (CT80 Rev B only) |
| set_point | Number:Temperature | The current temperature set point of the thermostat |
| status | Number | Indicates the current running status of the HVAC system |
| fan_status | Number | Indicates the current fan status of the HVAC system |
| override | Number | Indicates if the normal program set-point has been manually overridden |
| hold | Switch | Indicates if the current set point temperature is to be held indefinitely |
| day | Number | The current day of the week reported by the thermostat (0 = Monday) |
| hour | Number | The current hour of the day reported by the thermostat (24 hr) |
| minute | Number | The current minute past the hour reported by the thermostat |
| dt_stamp | String | The current day of the week and time reported by the thermostat (E HH:mm) |
| today_heat_runtime | Number:Time | The total number of minutes of heating run-time today |
| today_cool_runtime | Number:Time | The total number of minutes of cooling run-time today |
| yesterday_heat_runtime | Number:Time | The total number of minutes of heating run-time yesterday |
| yesterday_cool_runtime | Number:Time | The total number of minutes of cooling run-time yesterday |
