Wait for mqtt on startup #41

Closed clockbrain closed 2 months ago

clockbrain commented 10 months ago

Launching cec-mqtt-bridge on boot has problems if mqtt hasn't already started. This change puts the bridge into a loop on startup until mqtt is available. The change also ignores incoming mqtt messages unless the cec_class has been configured.

Also reduce the log level of cec refresh.

Note that running cec-mqtt-bridge as a service means mqtt can be configured as a prerequisite service which I do but this wait for mqtt on startup change adds that little bit extra protection. For reference here is my bridge.service file:

`Unit] Description=CEC MQTT bridge After=network-online.target mosquitto.service

[Service] ExecStart=/opt/cec-mqtt-bridge/bridge.sh Restart=always User=xxxxxxx Group=xxxxxxx SyslogIdentifier=cec-mqtt-bridge

[Install] WantedBy=multi-user.target`

what about if mosquito is not running on the same machine?

Fair point. So leave that entry out of the bridge.service.

Doesn't impact the PR though which waits in a loop for a connection to the broker via mqtt_client.connect()
