Multiple frequencies for RFRecv, rc-switch

[bilogic]

Have you looked for this feature in other issues and in the docs?
Yes

Is your feature request related to a problem? Please describe.
RFRecv supports only 1 receiver per microprocessor today, this makes it impossible to support multiple frequencies at the same time.

Describe the solution you'd like
Make RFRecv support multiple receivers, e.g. 1 x 315Mhz and 1x 433Mhz together

Describe alternatives you've considered
Using 2 microprocessors, which is quite a waste.

Additional context
There is a tested working proof of concept here https://github.com/BCsabaEngine/RCSwitch and I'm prepared to write the PR code, but need some help understanding Tasmota code

1. I'm reviewing https://github.com/arendst/Tasmota/blob/development/tasmota/xdrv_17_rcswitch.ino and have some trouble understanding how to work out which pin RFRecv is attached to.

I may have more questions along the way. Thank you.

(Please, remember to close the issue when the problem has been addressed)

RfInit();

Been reading https://tasmota.github.io/docs/API/#driver-sensor-energy-and-light-callback-ids but unsure how to know which pins have been assigned RFRecv. Any idea?

Thank you.

RFRecv supports only 1 receiver per microprocessor today, this makes it impossible to support multiple frequencies at the same time.

How about adding another wemos with another type of receiver? This is just a hardware change (using 434MHz or ie. 858MHz). I use it too on different devices.

Adding more interfaces to this software is more like a challenge and a can-do solution than adding anything usefull to it. It over complicates selecting user input and I feel it is of no use.

As for me, don't waste your time screwing up the code.

@arendst Yea, I'm starting to understand the code. I just figured out the part about finding all pins that are RFRecv. Sorry, I'm very new to Tasmota.

1. I assumed that it was possible to have multiple WS2812B on different GPIOs, is this correct?
2. I wanted to do the same for RFRecv
3. Do you mean it is not possible to have 2 x RFRecv?

Sorry. No. Only one led strip is supported.

I wanted to do the same for RFRecv

Sorry, won't be added for now. #10134 (comment)

Guys, it's done! I have RFRecv on D3 and D7 on my tasmota-sensor.bin in less than 20 lines of code changes. And everything is backward compatible!

The changes I made are scalable above 2 pins. However, I tested only 2 pins based on https://github.com/BCsabaEngine/RCSwitch, but his/her claim was it can go beyond 2 pins.

Please do have a look at my repo/PR shortly. Thank you.

Hi,

This was what I did to allow multiple definitions of RFRecv
bilogic@432f253

Is this something you guys will pull? If yes, I will merge my RCSwitch.cpp with the changes from #10063

Thank you.
