Does the Aranet4 work with RoamVitals?

The CO2 monitor van dwellers actually trust. It can broadcast, but only on request, and the layout moves between firmware versions.

Detected, decoding in progress

Not yet. The hub recognises the Aranet4 but cannot decode its readings, so it will show up as a detected device with no data behind it.

Before you buy, read this:

Requires Smart Home integrations to be switched on in the Aranet app before it broadcasts anything at all.
The broadcast layout is firmware-dependent, so we want a live capture before claiming a decode.

We are not recommending a purchase on the strength of this page. The hub recognises this device but does not decode its readings yet, so buying it today gets you a device RoamVitals can see and not much else.

Brand names are used here only to describe what RoamVitals reads. RoamVitals is not affiliated with or endorsed by Aranet.

How this device fits into RoamVitals

The RoamVitals Hub sits in your rig, listens for Bluetooth sensors like this one, and sends their readings to a dashboard you open in any browser. No app store download, no pairing dance, and no separate app per brand. Put a Govee in the fridge, a Mopeka on the propane tank and a leak detector in the wet bay, and they all land on one screen.

Set a threshold on any reading and RoamVitals alerts you when it is crossed. See how it works, or browse the full compatibility database.

RoamVitals is a monitoring and convenience product. It is not a smoke, carbon monoxide, LP gas, security or medical device, and it must never replace certified life-safety equipment.
