# Warmup Binding

This binding integrates [Warmup](https://www.warmup.co.uk) Wifi enabled Thermostats via the API at <https://my.warmup.com/>.

Devices known to work with the binding:

- [Warmup 4iE](https://www.warmup.co.uk/thermostats/smart/4ie-underfloor-heating)
- [Warmup Element](https://www.warmup.co.uk/thermostats/smart/element-wifi-thermostat)

Device expected to work with the binding:

- [Warmup 6iE](https://www.warmup.co.uk/thermostats/smart/6ie-underfloor-heating)

Devices which might work with the binding:

- Other similar looking devices marketed under different brands, mentioned in the API
  - [Laticrete](https://laticrete.com/)
  - [Rointe](https://rointe.com/)
  - [Porcelanosa](https://www.porcelanosa.com/)
  - Equus
  - [Savant](https://www.savant.com/)

Any Warmup device must be registered at <https://my.warmup.com/> prior to usage, or connected through the [MyHeating app](https://www.warmup.co.uk/thermostats/smart/myheating-app).

This API is not known to be documented publicly.
The binding api implementation has been derived from the implementations at <https://github.com/alyc100/SmartThingsPublic/blob/master/devicetypes/alyc100/warmup-4ie.src/warmup-4ie.groovy> and <https://github.com/alex-0103/warmup4IE/blob/master/warmup4ie/warmup4ie.py>, and enhanced by inspecting the [GraphQL endpoint](https://apil.warmup.com/graphql).

## Supported Things

The Warmup binding supports the following thing types:

| Bridge         | Label             | Description                                                                            |
|----------------|-------------------|----------------------------------------------------------------------------------------|
| `my-warmup`    | My Warmup Account | The account credentials for my.warmup.com which acts as an API to the Warmup device(s) |

| Thing    | Label | Description                                                                                    |
|----------|-------|------------------------------------------------------------------------------------------------|
| `room`   | Room  | A room containing an individual Warmup WiFi connected device which controls a heating circuit. |

**Room**
The device is optimised for controlling underfloor heating (electric or hydronic), although it can also control central heating circuits.
The device reports the temperature from one of two thermostats, either a floor temperature probe or the air temperature at the device.
It appears to be possible to configure two devices in a primary / secondary configuration, but it is not clear how this might be represented by the API and hasn't been implemented.

## Discovery

Once credentials are successfully added to the bridge, any rooms (devices) detected will be added as things to the inbox.

## Thing Configuration

### `my-warmup` Bridge Configuration

| config parameter | type    | description                                     | required | default |
|------------------|---------|-------------------------------------------------|----------|---------|
| username         | String  | Username for my.warmup.com                      | true     |         |
| password         | String  | Password for my.warmup.com                      | true     |         |
| refreshInterval  | Integer | Interval in seconds between automatic refreshes | true     | 300     |

### `room` Thing Configuration

Rooms are configured automatically with a Serial Number on discovery, or can be added manually using the "Device Number" from the device, excluding the last 3 characters. Changing the target temperature results in a temporary override to that temperature, for the duration configured on the thing. This defaults to 60 minutes.

| config parameter | type    | description                                                        | required | default |
|------------------|---------|--------------------------------------------------------------------|----------|---------|
| serialNumber     | String  | Device Serial Number, excluding last 3 characters                  | true     |         |
| overrideDuration | Integer | Duration in minutes of override when target temperature is changed | false    | 60      |

### Run Mode Statuses

These run mode statuses are defined for the API.
The descriptions are based on inspection of the device behaviour and are not sourced from documentation.
Only the value `schedule` is writeable, this reverts the device to the program/schedule configured on the device.
The value `fixed` can be set by commanding the `fixedTemperature` channel. The value `override` can be set by commanding the `targetTemperature` channel.
