# Guntamatic Binding

The Guntamatic Binding can be used to monitor and control [Guntamatic Heating Systems](https://www.guntamatic.com/en/).

## Supported Things

The Guntamatic Binding was developed and tested using Guntamatic Biostar 15kW Pellets Heating System, running Firmware 3.3d.
It should work for all other Guntamatic Heating Systems as well, that support the same web interface (Pellets, WoodChips, EnergyGrain as well as Log Heating Systems).

- <b id="f1">1)</b> ... Channel is supported by Biostar, Powerchip, Powercorn, Biocom, Pro as well as Therm only [↩](#a1)
- <b id="f2">2)</b> ... `MANUAL` is supported by Biostar, Powerchip, Powercorn, Biocom, Pro as well as Therm only [↩](#a2)

#### Response of Control Channels

- `{"ack":"confirmation message"}` ... in case of success
- `{"err":"error message"}`        ... in case of error

The reaction of the Guntamatic Heating System can be monitored via the corresponding data channel. E.g. `program-hc-1` if you triggered `heat-circ-program-1`. The data channel gets updated with the next cyclic update (according to the `refreshInterval` configuration).

### Status Channels

The Binding dynamically generates Channels, derived from the data provided from the actual Guntamatic Heating System.
