The logs from the ESPHome device show that it has the sensor value. When I try to write it out to my e-ink screen, I get NaN, or garbage in the case of a text sensor.
This is, as you might say, frustrating.
Fixed it. Not sure how, apart from copying and pasting from code I found online (I have an inkling that I over-simplified previously, and it was updating the display before it had retrieved the data from home assistant).
Now (well, after work, obvs ;-) ) it's time to make it pretty.
The cheap ikea picture frames have arrived, and my displays are almost ready to deploy - on in the house, and one in my office (I don't need a QR for my wifi, and the house doesn't need to know my office CO2)
