I’m using a harmony hub to control my projector, Soundbar and various hdmi sources together with an Benq W1070+ projector. Everything fine (even when there is only a one way IR communication between the hub and the devices).
I stumbled over the Benq binding and found it interesting to see the lamp timer and source selection and to have a bidirectional interface to openHAB. I assembled wlan to RS232 bridge using a ESP8266 for under 5€ - nice (If anybody is interested I can post a little how to (no soldering no programming required!). The binding work as expected … BUT. The IR receiver seems to be switched off when the projector is in standby. So the harmony hub cannot switch the projector on again. Switching OFF works, so I think its not a hardware problem. Ups. Switching the Beamer on via openHAB -> WLAN -> RS232 indeed works. This makes sense if you want to limit the access to the projector i.e. Schools or universities.
Do anybody have the same experience (I don’t think many people are using this Binding - who have RS232 connections between openhab and their Beamer and WLAN/RS232 bridges are rare and quite expensive)
I could use a rule to detect if the harmony is in an action where the projector is required and switch the beamer on via RS232. But this could fail and I think it is one unnecessary step.
QUESTION: Can be there a universal way to send any serial commands (not only the few implemented in the binding) to a) use other commands and b) to use the command which seams to activate the IR Port.
Write Remote Receiver-front <CR>*rr=f#<CR> Write Remote Receiver-rear <CR>*rr=r#<CR> Read Remote Receiver Status <CR>*rr=?#<CR>
Or did I missed something?
Sorry for my bad english
