One Item switching another item

Setup, Configuration and Use Beginners

I am relatively new to openHAB and have started to successfully set up a test server on my RPi with a CUL module. Everything is working fine so far. I have defined two items, both switches, one that receives FS20 commands form a remote and another that can switch an InterTechno Radio Plug Sockets. On their own both work fine, but what I am looking for is: if I send a FS20 ON Command, the InterTechno Socket should get an ON Command too (and vice versa).
I read a lot of Beginners guides about Items but could not found how I achieve this behavior. Only with rules I was able to get that behavior:

rule
"FS20 to Intertechno"
when
    Item FS20Test received command
then
    sendCommand(ITTest, receivedCommand)
end

But as I have a few InterTechno Sockets that should be controlled by FS20, I wish there would be an easier way to get there. Maybe with item groups (one item in a group switches all group items)?

Thanks in advance for your help :slight_smile:

It’s way eysier, the only thing to do is, to double bind the items, so instead of

Switch FS20Test {fs20="C04B00"}
Switch ITTest {culintertechno="type=fls;group=I;address=1"}

plus rule for switching, just set up

Switch FS20Test {fs20="C04B00",culintertechno="type=fls;group=I;address=1"}

This would transmit all signals from fs20 in question of “C04B00” to culintertechno (and vice versa)

The Group itself can be treated as an Item. If you define the Group as a Group:Switch and you send an ON command to that Group, all members of the Group will receive an ON command. NOTE: all members of the Group must be able to receive and process an OnOff type command.

Thanks for the quick and helpful answers :+1:! @Udo_Hartmann than’s exactly waht I was looking for. Couldn’t find any infos about adding more than one binding to an item.

Sorry for reopening this topic. I tested @Udo_Hartmann solution with my server and it only works half way: if I switch the Item in Web UI, both bindings get activated. So e.g. both FS20 and InterTechno send an ON command (actually FS20 must not send, I want to use it for receiving only). But if I send an ON command via FS20 remote, the switch is updated correctly in Web UI but the InterTechno binding is not triggered.
I had my server running in debug mode and found out that if I switch the switch in Web UI, the item receives an command but when I send a FS20 command the item only gets updated (and wouldn’t trigger any other bindings). Is this a FS20 problem or do I have to set any additional parameters for the binding or item?

Thanks again in advance for your help :slight_smile:!
