Can i change the auto- refresh rate to 1 hour in the child app by simply changing the 30 to 60 on lines 37 and 91 ?
Yes, changing runEvery30Minutes to runEvery60Minutes will work.
Reporting back a week later. My simple 'refresh command seems to work OK with my front door lock, but it is not working with my back door lock. Looks like I'm going to take the plunge into installing OPC: Other People's Code Am going to try jwetzel's "Reliable Locks"!
UPDATE: That didn't help. Because my lock is simply gone from the network. It doesn't respond to the device page either... sigh.
