Potter Amseco ODC-59A Overhead Door Switch

needed a sensor to report to Wemo when the garage door was open.

I used these to create a raspberry pi based garage door alert for when the doors are left open accidentally. So far, so good. I removed the magnetized bar from the bracket and attached it directly to the top edge of the door. Besides the screws and washers holding the bar to the bracket, there are no mounting screws, so youll need some for the receiver and bracket.

High quality. Lasts several years when exposed to weather. Braid is good quality and reasonably long. Sturdy molded plastic can withstand very heavy vehicles driving over it.

I purchased this along with the Schlage RS100HC V N N SL Home Door and Window Sensor to use with my Vera Lite Z-Wave System. Everything worked great and you can see the external contacts and how I mounted it on the top of my garage door in the attached pictures.

This thing wired up in a few seconds and provided a much more reliable easy to mount solution for my garage door sensor. I had a cheap plastic white sensor wired up first and it was a pain to get to reliably recognize and would also keep shifting and getting dislodged. This thing comes with a serious bracket and plenty of ways to confidently mount. Plus the most important part, it has a very generous tolerance on the sensor, so placement is nowhere near as precise as the little cheap plastic magnetic sensors you can get in bulk

I expected this to be a complete unit. It does not contain the electronic part that attaches to the wall. I cant use it without the electronics. The electronic motherboard on the wall is larger than the one on my other contacts, and I have not found a way to order a replacement for that. Until I do it is dead in the water and useless.

Works fine but the one I received was NOT normally open as some of the answers to that question said.... it was normally closed. It did read 59A on the package. No big problem but, since I was connecting this to my home automation computer whose scripts I had written for an NO contact, I had to go back and change all of them. It works well, however, and appears well made for the price.

Great replacement, the holes were closer than the Honeywell switch it replaced, so I had to drill new hole in concrete.

Works great. Seems to be very durable.

Heavy duty switch. Easily mounted over the door and wires to my WeMo Maker.
