In light of WMKR's posting of losing his rays due to a power failure (terrible loss), does anyone use a backup or monitoring system for their rays? I have looked at using a Generac Backup generator system that connects to your electical panel with an automatic transfer switch that comes on when the power goes out. System is connected to the natural gas supply to the house for a fuel source. You can select certain circuits to be connected to the generator or operate your entire home off of the system (roughly $5,000.00 to purchase and install). I've also looked at an alert system (Freeze Alarm or Home Sitter) that will notify you by phone if the power goes out, house temperature rises or falls past certain temperatures and even has a water sensor for leaks (roughly $100 - $250.00). I've also been told there are a few apps you can get on the iPhone for monitoring your fish tanks. The last 2 systems would require a backup plan in place (generator, friend to check if you are away or unavailable, etc.) Does anyone have any experience with these systems or have an alternative system that they use?
