For pimatic I think there a not a lot usages.
I want also to control my max! heating system. I am waiting for my CC1101 wireless chip for that.
Cul self-construction, which chip? CH340G or FT232RL

@koffienl
the cul is a transceiver for RF communication, especially 868 MHz.
you need it e.g. if you want to connect to the homematic hardware or max! heating components directly.
for pimatic especially there is a pimatic-homegear plugin (for communication with homematic hardware) and the max-cul plugin for direct communication with the max hardware without gateway.

Is this something to incorporate into ESPimaticRF ?

well, i am no programmer but i guess this would be hard to achieve i guess.
you need a special transceiver and the cul fw.
feel free to have a look into the matter. it would be an outstandig feature of course!
maybe a @developer with more knowledge on homematic and CUL can help any further?

Yeah, don’t have anything of that kind stuff, can’t really say for sure it is something that fits in the ‘homeduino’ part of ESPimaticRF

Sorry for renewing a week+ old thread, but I have an issue that I hope a more experienced user can help with. I have two CH340g devices (Arduino Mega Clones) connected to a usb hub and both are connected to different ports; however, only one device is being recognized with the installed CH340g drivers. I am using Labview to interface with the Arduinos and thus require 2 active USB to Serial connections (2 separate COM ports) in order to communicate with both devices. I’ve gathered from this post that it might be impossible to uniquely identify multiple 340 devices because they all carry the same Serial ID. Have any of you ever encountered this issue? if so, did you come up with a solution? Any help and suggestions would be greatly appreciated!
Did you try this already?
/dev/serial/by-path/
It does require to use the same USB ports each time.
@rikki78 So it’s basically impossible to have two separate COM ports communicating with two CH340g devices? In that case, what if I replaced one of the Mega clones with an authentic FTDI chipped one? Would there be any issue when communicating with both the clone and the authentic one? From my experience you can have as many com ports as you want when communicating with the FTDI Megas, but maybe there’s a compatibility issue I’m not aware of?
@Kurobuta No it is not impossible, you have to address the USB ports in a different way. So instead of USBttyx use the /dev/serial/by-path/
