Studer
This extension adds support for the Studer protocol.
Studer Innotec, founded in 1987 by Roland Studer, is an ISO certified company that develops and manufactures inverters, inverter/chargers and MPPT solar charge controllers to communicate over the Modbus protocol entirely in Switzerland
For a list of certified products see this page: https://www.studer-innotec.com/
Supported Things
This bundle adds the following thing type to the Modbus binding. Note, that the things will show up under the Modbus binding.
| Thing Type IDs | Description | Picture |
|---|---|---|
| bsp | For BSP that offer a highly precise measuring for Xtender, VarioTrack and VarioString systems |  |
| xtender | For the Xtender models for system capacities from 0.5kVA to 72kVA that allow for the optimal use of available energy |  |
| variotrack | For the VarioTrack models of MPPT solar charge controllers for systems with solar PV capacity from 1 - 75kWp |  |
| variostring | For the VarioString models of MPPT solar charge controllers for systems with solar PV capacity from 4 |  |
Thing Configuration
You need first to set up a Serial Modbus bridge according to the Modbus documentation. Things in this extension will use the selected bridge to connect to the device.
For defining a thing textually, you have to find out the start address of the model block and the length of it. While the length is usually fixed, the address is not. Please refer to your device's vendor documentation how model blocks are laid for your equipment.
The following parameters are valid for all thing types:
| Parameter | Type | Required | Default if omitted | Description |
|---|---|---|---|---|
| address | integer | yes | first slave of device |
Address of slave |
| refresh | integer | yes | 5 | Poll interval in seconds. Increase this if you encounter connection errors |
