‘just enter your email address…’ WHERE am I supposed to enter it ?

@nedy, a little confused by what you mean.

Are you going to this page to sign in? https://my.bulb.co.uk/login.
That’s the same page that a link clicked in an email should send you to if you’re not logged in.

When you’re logged in, you submit readings from your MyBulb page.

Or am I well off the mark and you’re being presented with that message somewhere else?

@nedy As @mowcius said, let us know where you are seeing this message and we can help out and see if this is an error we can sort out.
