eQ3 thermostat full list of install commands?

Having had a eQ3 running some time ago, I tried to revive it. As I had problems getting my old install running, I installed a fresh hasbian on my raspberry pi 3.
While the command “sudo pip3 install python-eq3bt” succeded, the command eq3cli --mac 00:1A:22:06:5E:0B fails with 'ImportError: No module named ‘bluepy’.

I had pip-installed bluepy and also tried to manually compile it as suggested in other discussions, but without luck… I wonder if someone who got the device running, could please share all the required steps?

Thanks a lot in advance! Keep up the great work!
