That's a nice approach. Do you control the radiators using other inputs? Our current system works using a CalDAV calendar with repeating appointments providing information about work/home/sleep times. This is combined with presence detection using our mobile phones and Z-Wave motion detectors. This also controls lights, light color temperature and our ventilation system. All events go to InfluxDB / Grafana combo. OpenHAB 2 is the spider in this web of IoT stuff.
