Camera for meter reading

How do you use camera to send electric meter readings. Tried today and could not get it to take picture.

Not enough detail as to whats wrong.
Is it taking a picture OR in trying to send it to Bulb?

Hi. Used bulb app to send meter readings it asked if I wanted to take pic said yes but couldn’t find a button to take pic. It showed meter on screen but can’t figure out how it takes pic.

You take a picture with your mobile or camera and attach it to an email to send.
It doesnt send from the meter.
