Sorry, for such a noob question, but I’m really stuck here. I have very little (no) programming experience prior to discovering node red last year. I’ve successfully created a few projects, the biggest controlling a window air conditioner to cool a walk-in cooler down to 45 degrees with notifications, etc.
I would like to use this lcd to display the cooler temperature and the air conditioner coil temp. I have ds18b20 sensors getting this data.
I’ve tried every i2c node I can find, and every sample flow on this site. I’ve successfully gotten the screen to print out pre-defined text, or the current date/time using This flow although my screen is 2 lines.
Where I’m stuck is figuring out how to display the data from the sensor instead of pre-defined text. I assume this is because the msg type is incorrect for how the flow is set up, but I’m not sure?
I would really appreciate any help - I’ve spent an embarrassing amount of time on what I thought would be a very simple part of my project!
Edit: the display is a generic 16x2 lcd with I2C board from aliexpress.
