I'm wondering if you can help me here. For the last week I haven't been able to connect to the growatt server from my web browser and this started when a new 'verification code' option appeared as part of the normal login process. It seems that I need to type in a 3-character 'verification' code (which is shown on the screen at the time) but I always get 'Username or Password' error (at which time the verification code changes to a new 3-character code). Note if I don't enter the 3-character code correctly I get 'Verification Failed'.
However currently your WonderWatt system is still able to connect to my growatt system (using the same credentials).
Maybe you can explain how your login differs to what I am trying to do on my browser and hence how I might be able to get round the problem and login in myself?
Thanks
