When I need to do an update to a sketch, I don't have to physically access the boards. For the displays, I just attached the NodeMCU to the back of the display board and connect the micro USB to 5V.

    I have a couple of the boards buried in wall boxes and haven't touched them in a year or more.
    Thanks Randy - very cool. Not sure how you put all this together, but I'm in awe, and thankful for your willingness to share!

    Yes, they are wireless. This is the NodeMCU boards that work with the beta version of the plugin.

    Thanks - I was wonder about running wires for these things which are being reported, but wireless makes that simpler.

    Would you mind sharing a link? Looking for this a long time.

    Here is what I have. It is a 4x20 display mounted in a little stand I found on eBay. A NodeMCU board is attached to the back of the display and the whole thing is connected by a micro USB power cord.

    You dont need to create any devices. Use a replacement variable for the OneWire temperature in an event that updates one of the LCD lines. When I get to my computer I will post an example.
