Having a hard time finding RF transmitters and RF receivers that work with each other. On the receiver side, need it to receive ther signal and trigger the output to a NC (normally closed contact).
Anything out there that is reliable to do this?
Thanks, jt
I have had good results with Street Smart units.
There sources of modestly priced multi-channel pairs of transmitters if what you need can be 'stand-alone" that is not communicate with other systems.
Here's one eBay vendor:
"Reliability" needs to be defined. How far does the signal need to travel? What intervening materials (brick, metal siding, steel lath ...)? Does it need to work even next to a microwave oven that is on? Does it need to be 'secure' ? (And what does 'secure' mean to you?) And so forth.
