Receiver for Security+ 2.0 (to connect to ESP32) #26
Description
I'm seeking some pointers to get started with secplus. Sorry, I'm just starting out here.
I'd like to connect a receiver to an ESP32 (running ESPHome) and be able to identity individual remotes.
I see the remote_id is provided by the library:
Security+ 2.0: rolling=240124682 fixed=62088643072 (button=14 remote_id=1959100928)
Security+ 2.0: rolling=240124683 fixed=66383610368 (button=15 remote_id=1959100928)
Security+ 2.0: rolling=240124684 fixed=74973544960 (button=17 remote_id=1959100928)
I don't have an SDR, but I have a spare CC1101. I also don't understand how Security+ 2.0 works over the three frequencies (310MHz, 315MHz, and 390MHz), and if that would limit my use of a receiver like the CC1101.
Would a CC1101 work, and is anyone aware of using secplus with an ESP32?
My interest in this is that the 89xLM remotes are very inexpensive, have good range, and come in a handy package. I'm currently using an 850LM three-channel receiver connected to an ESPHome device to uniquely identify three remotes (or really, channels). But, if I could read the remote_id I could have many "channels" for mapping the remotes to various actions.
I assume I'd have to implement rolling code tracking on the receiving end, too, if wanted to keep that security feature intact.
Thanks,
