Heat pump monitor kit default username/password

Having installed the heat pump kit, bought in November 2024, trying to log in locally at the web ui with the default username/password emonsd fails. What should I use? Thanks.
I get an ‘ Username does not exist’ error

Contact The Shop. Support for the Heat Pump Monitor is included in the price.

Or it might be the one on the last page of the printed documentation supplied with the kit.
