Hi to all,
tonight I made update from 2.2.0 RC2 to 2.2.0 (stable) on my Raspberry PI3.
It is a live system (my heater control).
By the way the update is very simple.
First of all, backup or better CLONE your PI.
1 - Disable the daemon with
sudo systemctl stop mysgw.service && sudo systemctl disable mysgw.service
2 - Make a copy of the MySensors folder ( I made a copy with the name of version coming, so...)
cp -r MySensors MySensorsX.X.X(rc2)/
(the slash at the end means "It's a folder!"
3 - Remove the MySensors folder
sudo rm -r MySensors
4 - Git the "new" MySensors folder && configure it as usual. Remember to activate the daemon and see on Domoticz (for example) the gateway with new version
