Shine WiFi x datalogger exists but doesn't

Hi. I've taken over a growatt inverter install in the house I've bought.

I've managed to create an account for Shine Phone and add my residential plant.

Then I added, the Shine WiFi X datalogger which appeared to add OK but when I go back to plant it says I need to add a datalogger.

If I go to datalogger list I can see the logger and it says online.

Am I missing a step.

Having setup the datalogger led turns off.

I notice it says router password cannot have special characters (and my WiFi does). Is this what it it is referring to or something else)?

Any other suggestions welcome.

Thanks.
