I love playing with my HA and associated devices. I suspect that most of you reading this get a bit of a jolt every time you add and incorporate a new sensor, camera, integration and get to play with it.
I have all the door/window sensors and locks/covers, every angle of my exterior covered with cameras, alarm, network devices, appliances, sprinklers, household devices covered.
Any ideas for a new thing I can play with?

The CO2 sensor calibration thing is inherent in the technology. They drift, a lot, and without occasional reference to a known standard, there’s no way to know whether “1000” is really 1000, or 500, or 2000, but exactly how that gets implemented seems to vary a lot. I have an SCD30 board from Adafruit, which internally records CO2 minima and, over the course of week or so, adjusts its calibration so that minimum is 420. That means no special calibration procedure, but it does have to be somewhere that it gets periodic fresh air exposure.
There’s a newer, photoacoustic sensor technology that doesn’t seem to require continuous recalibration, but (at least this one: https://www.sparkfun.com/products/22956 ) require an extensive initial calibration.
Sorry for the late reply. That photacoustic one looks interesting. I have no issue with an extensive initial calibration when it then just works without me needing to take care of it regularly. Thank you :)
