mh-z19b dead? : esp8266 - reddit

I've had a MH-Z19B for a few days. It reported believable figures at first (the CO2 figure would rise when I was in the room for a while, would drop when I opened the windows, etc). But for the past few days, it's just always reporting 400ppm and 25C. I'm using a Wemos D1 mini with ESPHome. I have ABC disabled. It was polling every minute, I've now moved that to every 10 minutes but it doesn't ...
