230-240 volt, so yes it must be European CM11 as it is not the British version
It came with both USB cable and serial cable, I had bought the RS232 to USB adapter, then found I did not need it as the unit came with the USB cable too.
I also have the British CM12, with the USB cable too, that is currently at home, connected a RPi 3B+ and heyu bridge for use with Alexa.
I've got no access to all of that at the moment, but I did have a CM11 that I had bought by mistake with the non compatible Euro plug.
While laid up (6 months with a broken leg) I thought I'd get to grips with learning about programming the CM11/12 with basic schedules.
My one aim is is be able to have my router and network bridge unit auto re boot once a week or so to keep things 'fresh'
At present I can shut down the router remotely using a TIP10RF...but then as soon as the router is shut off..no network to turn it back on again..so looking for a way to issue a 'reboot router command' Macro to turn it off, delay 30 secons then back on
Have seen mention of Home Genie and I do now have it installed on the RPi, but all I need is the ability to send one or two basic schedules to the CM11. Is there maybe something else less complex than Home Genie that would accomplishg this ?
