#Velbus turned out to be the rock solid open home automation system, easy to extend and easy to integrate.
#OpenHAB link? No problem.
#HomeAssistant? No problem. Industrial 4..20mA or 1 to 10 V sensors? No problem. Relay output/input? No problem. Power measurement, access control, RGBW LED lights, meteo station to control window blinds. So far I could not find anything that can't be done with Velbus and OpenHAB 😍 I started a page to gather all Velbus related info:
