I never read there was an option in the Micra to adjust the brew pressure.
If I'm wrong, and there is an option to adjust the pressure significantly, then I'm will be purchasing the Micra myself.

You can adjust the pressure but you have to take the cover off the machine as far as I understand so you could set it to a flat 6 bar instead of 9.

Can it be switched on remotely via the app?
The mini can be turned on remotely so I'd expect the micra to have the same capability.

The Linea Mini has a typical pressurestat that allowed me to adjust the brew pressure down. Happy with the results.

Taking the cover off was just a few screws.

Is this a mistake? Do you mean an adjustable OPV to limit the maximum brew pressure?

No. Its how I prefer to regulate brew pressure.

There is an adjustable bypass valve on the rotary pump.

To clear up some confusion: Pressurestats are used to control the steam boiler temperature. I think you mean the rotary pump bypass valve. The Micra doesn't have a pressurestat -- it uses a PID type controller for the brew and steam temperature.

Does this adjustable bypass valve send excess water to the Micra water tank that is controlled by making adjustments in the valve?.
Therefore it is similar to an OPV valve except this bypass valve is connected to the pump motor output ?
Help..
