Remote Control 433MHz Schanz Rolladen with Raspi.
Using a minicul and the SIGNALduino FHEM module create an interface for a rollershutter using MQTT. FHEM is encapsulated in a separate container only for the purpose of sending the 433,95 MHz commands to the rollershutter motor. A separate container provides a python script for sending the commands to fhem and serving an interface using MQTT.
The following topics will be used:
| Description | Topic | Values |
|---|---|---|
| Set position | rollershutter/control_position/Test1 | 0-100 |
| Control | rollershutter/control/Test1 | Open, Close, Stop |
| State | rollershutter/Test1/state | open, closed, opening, closing, stopped |
| Position | rollershutter/Test1/percentage | 0-100 |
- 0% == Open, 100% == Closed
Thus this module is compatible with HomeAssistant and OpenHab.
Configure the following variables in the docker-compose.yml file:
MQTT_HOST MQTT_PORT FHEM_HOST FHEM_PORT TIME_OPEN TIME_CLOSE ROLLERSHUTTER_NAME.
(If the variable SIMULATION is defined, run in simulation mode.)
- Install mosquitto, i.e. on osx:
brew install mosquitto - Optionally use the dashboard using docker-compose described here
- Set position topic: 0-100
mosquitto_pub -h t20 -t rollershutter/control_position/Test1 -m 30 - Set control topic: Open, Close, Stop
mosquitto_pub -h t20 -t rollershutter/control/Test1 -m Open
mosquitto_pub -h t20 -t rollershutter/control/Test1 -m Close
mosquitto_pub -h t20 -t rollershutter/control/Test1 -m Stop
- State topic: open, closed, opening, closing, stopped -
mosquitto_sub -h t20 -t rollershutter/Test1/state - Position topic: 0-100 -
mosquitto_sub -h t20 -t rollershutter/Test1/percentage
