Great sensor

Been using this sensor for almost a year now, it has worked wonderfully. If I had to point something out, it would be that the measurements seem to be in the wrong units, e.g. it is currently measuring `513,000,000 ppm`, while the obviously correct value would be `513 ppm`. Everything else works wonderfully.

Just replace converter code.

Excellent seller

I ordered a CO2 sensor from ALab, as this seemed to be one of the best bang for buck ZigBee CO2 sensors available.

I was having issues pairing the first sensor that arrived, but received excellent support from ALab. We attempted various things to make it work, but eventually decided to replace the broken sensor. ALab covered the costs for the return and later messaged me he discovered what the issue was.

The second sensor I received unfortunately got damaged during shipping. This sensor was once again replaced.

The third sensor arrived in good shape and I was able to pair it without any issues. I've been using it with Z2M and Home Assistant for a few weeks now and it's been running great. I am planning on buying a bunch more to cover most rooms in the house.

ALab is an excellent seller with great products and even better support.

Works perfectly with Zigbee2MQTT

Really fantastic little prebuilt zigbee co2 sensor. Not only one of the cheapest around, but also the most plug-and-play for my MQTT use case. Readings are perfectly accurate and refresh at just the right rate for charting.
It wasn't clear to me from the description, but it can be powered by USB-C - you can ignore the DC input. I couldn't get it to power up connected to a PC, but no issues with any USB charger I tried.
My only complaint is the clearance around the USB-C port. Out of 10 USB-C cables I had lying around, only 2 were able to fit past the case and DC connector. Not going to dock a star for this as I've seen SBCs such as VIM3L with the same issue, but something to be aware of

Great SensairS-8 sensor, and PH sensor with Zigbee2Mqtt

I needed zigbee compatible Sensors with quality components, for use in Home Assistant automations.

ALAB ----has unique designs combining quality sensors and Zigbee communicators.
I use the Data provided by ALAB Zigbee CO2 and PH sensors for monitoring and control of hydroponic grow systems Wirelessly!

I have zero experience programing, but some Zigbee , Z-wave and Home Assistant experience.
I had a difficult time getting all of these "entities " to work together, but....

ALAB gave incredible support of the CO2 and PH sensors that I purchased,
AND further assistance to ensure that they worked nicely in Zigbee2Mqtt and Home Assistant.
A Remarkable Level of Support was provided. Thank you!

I plan on buying several additional Items.

Well built and works as advertised

I successfully integrated the device into my home-system on the first day after receiving it so I would say it is pretty user-friendly. I like the case and connectivity, the buttons labelled and the firmware works :)
