@Lolodomo Great binding, seems stable, although sometimes if I shutdown/start Openhab 1.8.1 too quickly, it fails to register with the Powermax.
The question I have is around the ‘autoupdate’ parameter, what is this used for? In the examples on the wiki, the value always seems to be set to false.
Your question relative to autoupdate is not specific to a particular binding. Someone provided a clear explanation on the forum few months ago. To say that simply, when set to false, your action only sends a command and does not change the item state. I let the binding update the items states.
For your problem at startup, can you provide any logs that could help me ? On what OS/machine are you running OH ? I am running OH on slow machines (RPI 2) and this never fail at startup ?
Can you tell me what Powermax model you own ?
