HLC setup for Rhasspy

Installation of HLC is rather simple and documented here

Installation

wget https://gist.githubusercontent.com/Psychokiller1888/a9826f92c5a3c5d03f34d182fda1ce4c/raw/cbb53252dd55dc4e9f5f6064a493f0981cf133fb/hlc_download.sh
sudo chmod +x hlc_download.sh
sudo ./hlc_download.sh

Before starting it, we will have to configure service file for Rhasspy.

The important command line parameters are:

–engine
–pathToConfig

Edit the service file and change ExecStart line as follow:

Adapt HLC version number, your profile path (en instead of fr ?) and your hardware if needed

sudo nano /etc/systemd/system/hermesledcontrol.service

ExecStart=/home/pi/hermesLedControl_v2.0.3/venv/bin/python3 main.py --engine=rhasspy --pathToConfig=/home/pi/.config/rhasspy/profiles/fr/profile.json --hardware=respeaker2 --pattern=kiboost

Then reload daemon and sart it:

sudo systemctl daemon-reload
sudo systemctl start hermesledcontrol

ReSpeaker button

HLC allow to map some function on button pressed. For this, edit your pattern file in hermesLedControl_v2.0.x/ledPatterns/yourPattern.py

Example toggling rhasspy wakeword:

```python from subprocess import call def __init__(self, controller): super(KiboostLedPattern, self).__init__(controller) self.host = '192.168.0.140' self.muted = False def idle(self, *args): #continuous blue breathing self.off() self._animation.set() middleLed = int(self._numLeds/2) if self.muted: self._controller.setLed(middleLed, 85, 0, 0, 75) else: self._controller.setLed(middleLed, 0, 85, 0, 75) self._controller.show() def onButton1(self, *args): #mute hotword detection: self._animation.clear() self.off() if self.muted: self.muted = False topic = "hermes/hotword/toggleOn" else: self.muted = True topic = "hermes/hotword/toggleOff" payload = '{"siteId": "'+self._controller._mainClass._me+'", "reason": ""}' self._controller._mainClass._mqttClient.publish(topic, payload) self.off() self._controller.idle() ```

Pressing the button will toggle wakeword service, and set self.muted variable accordingly so idle LEDS will show middle led green or middle led red if muted.

Turn LEDs on/off

HLC have topics to turn LEDs on and off. Just run this command on the master Rhasspy:

mosquitto_pub -p 1883 -t 'hermes/leds/toggleOn' -m '{"siteId" : "salle"}'
mosquitto_pub -p 1883 -t 'hermes/leds/toggleOff' -m '{"siteId" : "salle"}'

Tips

If you install several Rhasspy with a master and satellites, keep in mind that each device should have its MQTT host setting to the master IP.

debug

Start the service: sudo systemctl start hermesledcontrol
Stop the service: sudo systemctl stop hermesledcontrol
Restart the service: sudo systemctl restart hermesledcontrol
Show service log: journalctl -u hermesledcontrol.service
