I followed this initially and as you can see in the thread with a little help I go it working. But I had to make some changes so I reinstalled stretch and started from scratch and now I only get
(bellows) pi@raspberrypi:~ $ bellows -v debug permit
debug: Using selector: EpollSelector
debug: Loading application state from /home/pi/.config/bellows/app.db
debug: Sending: b’1ac038bc7e’
Anyone have any ideas?
