    it's absolutely not accurate for the temparture the readings are off. there's no way to calibrate the junk. the battery life without the 5v charger is less then 18hours . perhaps the electronics and screen are warming up the device to give false temperature. I don't know.

    Product Received within 15 days from ordering in India. CO2 detector seems sensitive enough. Tuya app adds the sensor readily and you can get the readings on the App anywhere once you add it. Good buy!

    It gets hot, so temperature measurements are higher and humidity lower. Particle measurements seams to be inaccurate.

    I couldn't get it to work without a battery. Without a battery, it only shows the charge...it won't turn on..... Powered by battery.....

    In the shop, I was wondering about the quality of the air, where there's plenty of dust. It doesn't measure the temperature well, perhaps because of the device's own temperature. If the air is not moving, the rest of the values are inaccurate. A more accurate value is displayed when e.g. If I put it in front of the air filter or manually move it through the air, you can really see when the air is dusty. That's probably because the dust doesn't move in the still air. The one I bought you for, like, a-a That's good, but it could be better. On the positive side, you got here so fast.

    On one hand: it is working, measuring the air parameters. On the other hand: I could not connect it to Tuya Smart App, which I have downloaded from Google Play Store. I am wondering: what can be the reason that there is NO AVAILABLE QR CODE in the user manual for the Tuya connection?

    The measurements it makes are unreliable and it needs daily charging. During the charging period, the ambient temperature increases by 3-5 degrees in the winter.

    Product does not work. CO2 sensor does not even respond to direct exposure to CO2 from compressed CO2 gas cylinder. Display light and others generate heat and makes temperature readings too high.
