And where does it get this “old” IP from ? , wouldn’t it be more appropriate changing the IP there( at it’s orign ) ( and keep your fingers from “core.config_entries” )
PS: I don’t know what SMA means in this context
This does not make sense( AND i doubt it’s any official places you read this), you should not make changes here manually. … seriously
Start by your integration, apparently an IP-device, So check your Router-Settings, if you have any DNS , flush-it/check-it, So if you take you SMA-Device down( and it’s default dhcp, and everything is “cleaned” for traces of you “unwanted ip number”) you should get a new from your router.
You could also start in this end " Manually setting the IP-number for the SMA-Device (Mac-binding).In Your Router
I have already set static IP in my router.
When I added my SMA Inverter I though that I should only have one Inverter but I have two.
It is not very important to change IP in integration.
I have all my IPs in different range depending of device.
There is a big difference in setting a static-ip, outside the dhcp-scope, and binding an IP within the dhcp scope
Depends upon whether you can set static-ip on your device, or if the device per default want dhcp
