I am putting this thread here to help others that might go down this road ( and Only because someday i will need this again no doubt)
I wanted to control my Solis remotely thru the SOlis CLoud app - but my version of the Data logger was too old.
So @graememk was very kind and sent me his one (and i will swap him my old one) THANKS!
The instructions/guide were wrong - it says connect to the new unconfigured logger SSID and use the serial number as password... it doesnt work unless you use the password: 123456789
The rest of the guide is fine - here is an online link that i used:
