For anyone having this issue:

Change the kms driver to the fake one by editing /boot/config.txt

change

dtoverlay=vc4-kms-v3d

to

dtoverlay=vc4-fkms-v3d

Reboot & display will now switch on/off using

vcgencmd display_power 0 vcgencmd display_power 1

I’ve not noticed any problems using the fake driver but I’m not using anything 3D (your results may be different)

Node js is one of the powerful tools of programming and using this if you are working on python it help you a lot. printer offline fix helped me to know more about python.

@sean Looks like I’ll be learning how to program in Java script :)

Thanks for the tips.

BTW: I found the issue with the python not running, seems the call from node changes the name of the script so main () had a different name to the import. Didn’t cure the snowboy issue (at least it got called, didn’t respond to wake word though 🤔, I’ll ask on the snowboy forum why that might be), but everything else worked.

I was thinking that MMM-Remote-Control was sending the notification, hence the confusion.

Cleaned the config up to look like this:

{module: 'MMM-Buttons', config: { buttons: [ { pin: 32, name: "monitor_control", longPress: { notification: "REMOTE_ACTION", payload: {"action": "HIDE", "module": "module_1_clock"} }, shortPress: { notification: "REMOTE_ACTION", payload: {"action": "SHOW", "module": "module_1_clock"} } } ] }},``

Can I add another payload from the same action i.e. hide clock & calendar?

Not had any success with that so far, can somebody give me a pointer to the syntax.

Ta.
