Majority of any e61 espresso machine is like that, pretty much par for the course for anything other than budget non e61 or some of the new high end espresso machines that use some variation of electrically heated groups.

Mine will be “ready” after about 15 minutes but as an e61 group head is a heavy block it takes along time to get good thermal stability. Difference is I can steam and extract shots at the same time with 2bar steam and 9bar espresso, shot after shot.

My espresso machine has a proper on/off switch, so I just leave that set to on and control the power from the smart switch.
