All entities stay unavailbale #112

Hello, i installed a controller with a sensor from our P1 port from the smart electricity meter. This sensor can vary + and - but now at time of trying it is just somewhere between 400 and 600. I also have a templated sensor from that one that divides the value by 1k.
I tried both these sensor now but all the entities are unavailable. i can't set a setpoint or anything else because they are all unavailbale and off course nothing else is happening too.
Allready removed controller and re-added, restarted HA (even full system restart) but stays the same.
In the logbook :
WARNING (MainThread) [custom_components.simple_pid_controller] Sensor sensor.p1totaal not ready; delaying setup

But these sensors are used on several other places too and they are really up and running...

What am i missing here ?

Thanks allready.
