I saw on github that in const.py the growatt server was deprecated…
See beneath…. Now I must look to change the one on my has-pi….
DEFAULT_NAME = “Growatt”
SERVER_URLS = [
“https://server-api.growatt.com/”,
“https://server-us.growatt.com/”,
“http://server.smten.com/”,
]
DEPRECATED_URLS = [
“https://server.growatt.com/”,
]
