In addition to the manual release option many of today's DC motor openers (often marketed as "ultra quiet" or "soft open/close") also incorporate a ~7Ah 12V SLA battery which can raise and lower the door several times when activated by RF remote. A few months ago I pulled up to my house on a lovely sunny day and wondered why my garage door was opening more slowly than usual, I was in the house a minute or two before I realized the power was out -- someone had hit a street-side transformer a mile or two away and power was out for 14 hours. Really a great feature if accessing the interior using a people-door is problematic (my mother's condo has _only_ the garage door, so the backup battery is great peace of mind). To stay on topic a bit: I found WiFi was not powered by the DC battery in my Chamberlain opener, just the RF for the remote and power for the wall mounted control. -Ethan _______________________________________________ Discuss mailing list Discuss@lists.blu.org http://lists.blu.org/mailman/listinfo/discuss
