mhz19b dead? : esp8266 reddit

I''ve had a MHZ19B 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 ...
