More questions: I'd like to use INPUT and OUTPUT RFlink functions for GPIO. To use GPIO INPUT I'd to enable using it by command: 10;setgpio=on after that short pins 26 to 29 to ground is reported (fine it's working ;-)) 20;04;GPIOset;ID=3;SWITCH=0;CMD=OFF; 20;05;GPIOset;ID=3;SWITCH=0;CMD=ON; output ...

Thank you for reply. To be 100% sure: to create ALL 10 "GPIO devices" I have to create devices using commands: 20;00;GPIOset;ID=000030;SWITCH=0;CMD=ON; 20;00;GPIOset;ID=000031;SWITCH=0;CMD=ON; 20;00;GPIOset;ID=000032;SWITCH=0;CMD=ON; 20;00;GPIOset;ID=000033;SWITCH=0;CMD=ON; 20;00;GPIOset;I...

I'm trying to use Mini GPIO output pins on my RFLink. I can turn it on/off using '10;GPIOset;31;0;ON; 10;GPIOset;31;0;OFF;' commands but now I need to allow to switch these 'devices' from Domoticz. Probably I had to create device 'manually' in Domoticz but I don't know how to do it. I've have found ...

Already done.

I'm using VentusW266 module (last version from github) and I'm quite happy with it. Unfortunately it look's that lightning strikes counter is NOT working (It always 0 via WWW) even when I can see "other number" at wheatear station LCD. Any ideas what could be wrong?

It looks that " 6 additional GPIO pin's" are OUTPUT pins number 34 to 39. In my case more useful would be INPUT pins. Maybe it's good idea to add (also) more input on free Arduino pins or make already used pins configurable as input/output?

Could someone point me to page with description of "generic GPIO usage"? Which Arduino pins etc.

OK, so I'm waiting for your impression WR-RY-6R.

Could someone please point me to good source of 868MHz receivers working with RFLink? There are plenty of 433MHz modules on ebay but I've not found 868Mhz version.
