Last week we had a tree come down on our power line to the house. This caused a surge over the neutral in our home. All the Z-Wave GE switches failed. And all my Cree and GE Link bulbs blew as well. Many of them letting out the magic smoke that they need to work (SMILE). So after 20 new switches being replaced very quickly (since I really missed not having them) I am now back up and running.
I have now added a whole house surge suppressor into my HA mix, along with a secondary protection at the incoming line into the house. So, if you do not have a whole house surge suppressor it might be a good idea to look into something, as when you have a huge surge it can be costly and time consuming to resolve.
