You can choose to operate your View monitor with batteries or connect it to power using the USB cable supplied with View monitor 😀.
The only difference this makes to functionality is that it changes how often information is pushed to the cloud and updated in the app/dashboard.
When View monitor is battery-operated:
You have 2 sampling rates to choose from:
Every 10 minutes
You can change this sampling rate in the web dashboard by following these instructions.
When View monitor is connected to power:
When connected to power, the values will update every 2.5 minutes (with the exception of radon which is still hourly).
Do I need to remove the batteries if connecting View monitor to power?
No, you can keep the batteries inside! However, they will not charge as only non-rechargeable batteries should be used. If there is a loss of power for some reason, View monitor will automatically switch to being battery-operated.
