Keyfob Gate Entry
« on: July 16, 2016, 05:38:32 AM »
This is a general request for ideas on how to accomplish the keyfob/moteuino portion.

I currently have a majority of this solution in place, meaning, Steps 3,4,5 are complete.

few questions in no specific order.
1.  can Moteuino interpret 433mhz keyfob signal from a device like this?

two.  can i use one Moteuino to listen to several different signals?

C.  doing a search on the word keyfob only showed two results, whats up with that?

general facts:

I have the end-to-end setup working by pressing a momentary button on the outside raspberry pi, it opens up nice and easy, but that would mean that i'm on the inside of the gate, with access to the button.

outside gets damn hot, like 50c or hotter on occasion.  surface temps obviously exceed that number.

I want to stick with a generic keyfob that works on 433mhz (legal where i am)   

I want to roll keys monthly, and rekey the keyfobs indoors, not where its hot out.

good start

Looks like a nice project, there are other similar ones (gate entry) shared in this forum.
I argue you might do away with the Pi's if your outside-inside is not kilometers away from each other. That would very much simplify your project, in addition to lowering cost.

1. Keyfobs? Maybe but i haven't done it, maybe others in the forum/web have with the RFM69. Definitely not with the RFM69 library.
two. Yes.
C. Probably because it's not a popular thing people have done so far.
