I’ve got a Qingping Air Monitor Lite - it’s small, not ugly, and from what I read at the time, has a decent CO2 sensor. It integrates perfectly with Home Assistant via Bluetooth. Seriously, no issues once I got it setup - which I believe did require their app to do initial setup/updates/etc… www.home-assistant.io/integrations/qingping/www.amazon.ca/…/B092HK4BB1
I have a ‘roll-your-own’ using an adafruit SCD-30 module www.adafruit.com/product/4867 IR-based CO2, temp & humidity; I2C with python libraries, so integrating it with an RPi is easy. Sensor is self-calibrating over time, so if you leave it in a higher CO2 space with no exposure to fresh air, it will eventually drift such that the lowest observed CO2 reports as 420 ppm. Newer SCD-40 is only $45, but different sensor technology.
I have done 3 and 4, and I definitely prefer the air gradient, it is a nice sleek little box that is flashable with esphome making it tie directly into HASS. Will be getting more of them in the near future.
That’s the same company that has this on their ‘about us’ page:
“Haier company history: since its creation in 1984, the company has been run by the same CEO, Zhang Ruimin, who has always had a clear objective: to build high-quality, reliable products. Within the first year of his appointment, in response to complaints about faulty fridges, his radical action of smashing the fridges with a hammer in front of employees has been recognised as an important cornerstone of the brand.”
Never considered buying Haier anyway, but i am looking specifically for appliances that have HAOS support. So them pulling this shit will put them on my black list for ever. I get why Mazda did it, but the car doesn’t need the app to be useful, i can just ignore that part. But this is an home appliance that looses a big part of it’s usefulness…
I have some sensors on a hognose enclosure and I can say for sure stay away from INKBIRD stuff. It integrates poorly and fails on loss of internet connection.
I don’t have a good solution for the heatmats yet but I’m looking into integrating an aquarium controller I have laying around to manage that.
For hygrometers there are a ton, but you’re going to want to look for low power and probably zigbee. the majority of the sensors I’ve tried have been an annoyance to manage batteries but the zigbee ones seem better.
Not sure what temp and humidity levels a terrarium is expected to have, but Shelly makes a good device for monitoring both - www.shelly.com/en/…/shelly-h-and-t-white.
Or one with a screen (still smart) - www.shelly.com/en-us/…/shelly-h-and-t-gen3-1/
We use the latter in our bedroom which triggers the power outlet to a humidifier if it gets too dry when we’re sick.
