Pete,
I had read your Feedback comments before attempting my conversion. Very helpful.
Yes, I am using MQTT. I’ve modelled my implementation after your work, My home automation projects built with MQTT and Node Red - Projects made with Blynk - Blynk Community.
I am happy to report I’ve completed my conversion and everything appears to be working as expected. I have implemented the LCD node and it is functioning for me.
To summarize my issue, the problem appears to have been an outdated version of Node.js.
Thanks again for helping find that solution.
Larry
