Hi all,

Longtime tinkerer, tech savvy, but a newbie with actual circuit design. First post.

I have a 2-button keyfob and would like to connect it to a WeMo Maker relay to perform the following two behaviors:

Close wemo relay (ON state): "Press" or activate (pulse) keyfob button A momentary switch
Open wemo relay (OFF state): "Press" keyfob button B switch

Is there a simple circuit I can build between the wemo maker and the keyfob that will result in this behavior? The keyfob is powered by a standard 2532 button cell, I believe.

Thanks in advance!

Carl's electronics has what you need.

 

Thanks for the tip about Carl's. They seem to have a great selection.

Can anyone follow up with any details about what exactly it is I might need, and how to construct the circuit I'm talking about?
