the device has the green led on all the time with the blue one popping up now and then

This is normal.

I would do a reset to default, using USB command “default” . It should simply respond “ok”.

If this doesn’t help, we’ll just do a firmware update on it.

what is the Device ID?

Do you need help with the firmware? I can compile it for you, to include this new tube. Let me / us know.

Hi Harms, we’re still here, yet the Forums see less activity in the last months. Some of the individual sensors on your A3 are no longer working due to them reaching their lifespans. You can still continue to use the Radiation, Temperature, Pressure, Humidity, VOC and CO2, but the PM and the Formaldehyde are EOL.

On the A4, do you still see the PMs as 0?

Glad to be of help.

Both the A3 and A4 are currently available,

Normally, the A3 could come with GSM connectivity, however the current design uses 2G / GPRS that was shut down in the US starting with 2023. I suggest using one of the alternatives instead, WIFI , LoRaWAN or Ethernet for the A3 . The A4 uses WIFI only.

Hello Ken,

You can change the mobile average interval yourself, using the “sendint” command via USB. If you increase the sending interval, the data will be averaged prior to upload to server.
