Hi
just recently installed homegear on a new stretch system. the current version is:
dpkg -l | grep homegear
ii homegear 0.7.12-1492 armhf Interface program to your smart home devices
ii homegear-homematicbidcos 0.7.12-1492 armhf HomeMatic BidCoS module for Homegear
ii homegear-nodes-core 0.7.12-1492 armhf Core nodes for Homegear's Node-BLUE
ii libhomegear-base 0.7.12-1492 armhf Base library for Homegear
ii libhomegear-node 0.1.6-21 armhf Node library for Homegear
I got the feeling that this is some steps behind homegear on jessie.
looking at the repository jessie shows 0.7.14 while stretch shows 0.7.12.
cheers
