Tested on a Solar Frontier Turbo 1P
The Solar Frontier converter must have a Static IP-address to get this flow working properly.
The whole Flow is made simple. There are a couple of things that have to be changed according to your own environment.
These are the InfluxDB, and the Http request node.
Change the Http request and IP-ADDRESS to your Solar Frontier IP-address.
The Timestamp is set to 10 seconds.
