I would vote for MQTT as the protocol for this, as I've used that all 
over my house for passing temperature and humidity measurements to a 
central database (influxDB) to track all that. The code for MQTT is 
available in python, c++, circuitpython, ardunio, etc. The Leanfront 
code would just need a setting for each event like "topic" to subscribe 
to, etc.  I'm not using HomeAssistant, as I did my own stuff with NodRed 
which centralized the data between MQTT, influxdb, grafana, and 
clients/endpoints.
