CO2 Air Quality Monitor For Home Alerts

Excellent sensor, there is a lot of good feedback about it, I will not write about it.
I will only add that without any problems it will be thrown into zigbee2mqtt and further into ha and further into Alice through Yaha cloud.
The sensor transmits values every 10 seconds.
The only minus is a very large case, I will think about the smaller case model for the 3Dprinter

🔥NDIR🔥
Bought a sensor with ZigBee protocol. Without any problems hooked him to the Alisa midi.
Set up the script for a notification-everything works.👍

PS. Bought for 1768 rubles in November 2024 (including delivery)

The board is not large, and the box itself is large. I quickly connected with the program, everything works and really shows the changes in CO2. Flashing with constant frequency, probably this is the measurement. The indication does not change from the level. To use the scenario for ventilation what is needed.

The figure is relatively accurate. I'll use it well.

Zigby does not connect to Yandex stations (tried on Max from Zigby and Station 2). In zigbee2mqtt without additional tambourine dances does not work. From smart life to Alice also does not throw. In the smart life itself works well, the readings are updated once per second

In principle, everything suits. The truth, with some reservations, does not throw into Alice either directly or through smart life, she simply does not see it. Managed to throw only through the home assistant. But here the home assistant itself is not cheap on VPs, if there is no mini-PC. The path will be as follows: smart life, then home assistant, then Alice.

The sensor is solid, it was taken by reviews
At the moment it is not clear for what reasons he does not reach for the Yandex hub
Round Zigby took

Accidentally took both versions. In zigbee2mqtt and home assistant were added without problems. I have been using it for a couple of months, the readings are correct. The dimensions of the photo. The round one is attached to the wall through a transitional plastic strip-the strip is screwed by 2 self-tapping screws, and the sensor sits on it in half a turn. Square-only 1 screw. Micro USB connectors, I would like Type C already in 2024.

Arrived quickly, connected easily. Of the minuses: a large box. The staring bright yellow indicator will give birth, it will not be delivered in the bedroom, it will interfere. In the Google home is not defined.

Connected without any problems, automation works. I will order more!

It works well at Z 2m ha.

Clearly monitors the level of carbon dioxide and gas. Made only smart life, no in Alice!

Works. Hooked without problems, the data is updated often. Micro USB as power, 2024 looks strange. The wiring included is short, only test. Will have to look for another for normal connection or extension cord.

Good product.

Everything works.
Connected to Z2M, only transmits CO2 value

An external converter file is required for the zigbee2mqtt to recognize the sensor. Done that, it works well.

Well attached to Smart Sings

Work with ZHA (TS0601 by _TZE204_ogkdpgy),Device Type: Router

Everything is fine. thank you

Plugged In, tuned in. Works. The readings show in the app. All Horosho. This is the second sensor. Thank you

Works norms. Smart Life app. I will order more

Differs in readings from another manufacturer by 5 percent. generally good.

Connected to the Gateway without problems, the values show similar to the truth.

That's what I did to him. Initially, of course, he was probably a worker, and since I do not and will never have this Tuev hub, I accordingly could not see any data. The product is the result of the next efforts of our friends towards monopoly.
And there is a CO2 sensor there-it works completely autonomously and responds to the USART command with calibrated data. And there is another vile controller, if this device does not give away in addition to CO2, it remained a secret for me. The ZigBee module, due to its worthlessness and working in tandem with this controller, were eliminated and replaced by the usual folk esp8266. With the help of small modifications on the board and downloading the firmware from the esphome sensor mh-z19, it was possible to achieve the desired result-updating the data once a minute is more than enough.
Summarizing, from the fact that there was a case with a board (power supply for everything necessary), a sensor and a module-I should have bought only this sensor for a thousand rubles and not fooling myself

Gives good indication probably too high values than in reality

Everything works as it should be, a real sensor, almost immediately sees the difference when moving from the street to an unventilated room from 400 to 1200.
Connects to smart life simply.

Very fast delivery. Quality product. I recommend.
