Or… leave the batteries out. What is really going to run when you have a power outage? Not your router or lights. I also like the fact that the ST hub will reboot along with the rest of the devices when power is restored. Regardless, in a power outage you get a push message that your hub is not communicating.
You probably know this but, the standard fix for most issues is to take out the batteries and disconnect the power line for 10 minutes. Then replace, forcing a full reboot.
Is it just me, or does support like to blame community device handlers/smartapps for user issues that turn out to have nothing to do with the actual problem?
I had a linksys router that kept doing that to me also. I also had problems with my internet provider hardware due to moisture out in the box. Mice seem to like to eat the cables also from time to time.
