Can the RX433 shield be used to decode Directv RC 73 remote

315MHz and 433MHz wireless connections are very commonly used by consumer electronics including weather stations, home automation remote controls, power consumption meters, car alarms, and also many DIY projects.

Can the RX433 shield be used to decode Directv RC 73 remote

Post by Bwanajohn51 » Thu Sep 12, 2019 4:10 pm

I am in the process of making a softball scoreboard. My prototype uses an IR remote to control scores, outs, innings, etc. Since the final version will be out in the bright sun, I would like to use an RF remote in place of the IR remote. Will the RX433 be suitable in this application? Does anyone have an experience using a similar TV remote or similar application?

Thanks

Haven't heard of anyone doing this. I think you would have to do your own decoding which may be a challenge. Maybe if you could get hold of the receiver/decoder from an old set it might make your task easier.
Do they even run at the same frequency? The 433mHz band covers a range of frequencies.
Also the RX433 is very prone to noise problems with resulting erroneous output.
