    Hi Hirez,

    Please try a different power supply. I had it once….a defective (glitchy) wall wart did not allow my monitor to properly boot. It got an IP, and the IP listing on the access point shows an IP even when it rebooted in the meantime.

    Hi Brandon,

    Try another wall wart adapter. The ones coming with the sensors are crap. Capacitors inside the wall wart like to fail, which makes the 5 volts supply unstable.

    Hi,

    Your unit actually /does/ show up properly, see my screenshot.
    Could it be you forgot to check the “Show indoor units” box?

    Hi Volodymyr,

    Yes, it is officially possible to export data from sensors.
    Go to your dashboard:

    Dashboard


    Then click on the API tab. There is a description how to do export data from sensors.

    Slava Ukraini!

    Hi,

    What variant is it? Ethernet, Wifi or LoraWAN?

    Sorry to hear that!
    Have you tried another power supply? These “wall warts” are pretty unreliable and start to dish out a lot of spikes, which disables the unit.
    I had the same problem with my unit. The problem disappeared after opening the wall wart and replacing all the elecrolytics, since they were dried out.

    What sensor type is it and which ID does it have?

    Hi Paul,

    Well, if I take a look on the world map after selecting radiation and indoor units there is only one unit in Kyiv:

    There are several more, for instance in Moldova:

    OK, if I understood you right, you want to connect a passive unpolarized buzzer to the “pulse output” of your circuit diagram, correct?
    First, you need to test if the buzzer is loud enough if you just feed it with the 2 batteries power (3 volts).
    If it is, put that buzzer instead of R3 and you are good to go.
    If not, you’ll need a second transistor stage that inverts the “pulse output” via a 10k resistor and an additional NPN transistor. Connect the buzzer between the collectors of the two transistors. That will almost double the voltage across the buzzer.

    I do not really like that HV generation circuit, since it produces unregulated HV. That will lead to varying sensitivity and spurious clicks.
    Do you have an oscillscope to take measurements?

    Hi,

    Since I had experienced a similar problem with my Smoggie, I’d suggest you try a different power supply, it could very well be it shows exessive ripple on the 5 volt rail, which can affect operation of your A3.

    Which unit is yours?

    Cheers,

    Hi Maros,

    Its best to contact Radu about this.
    When I bought my Smoggie back in 2020, I did get a proper invoice from company “MAGNASCI SRL” via PDF.

    Hi Ghosh,

    Can you show what the circuit looks now?
    I’m happy to help you out, but I need to know from where we’re starting.

    Hi Mihai,

    Have you checked “show indoor units” checkbox in the left (“Radiation” in your case) window?
    It is a flaw in the current website version, that your map doesn’t seem to remember the switches set.

    Cheers,
    Wolferl

    Or select “Show indoor units” on the map 🙂

    Glad you got it going!

    Hi Brian,

    I agree with you. It would be great to have kind of a “Super KIT1” PCB that has the option to put the sensors on it that you are interested in.
    That thing would be quite big, though.

    Cheers,
    Wolferl
