Following on from the previous Givenergy API post, an alternative method is to use Node-RED which uses “flows” to manipulate data.
Looking to use Powershell or learn more about API’s in general? See here
The default flow for the Givenergy API would give you a basic display such as the below:
From this starting point you can manipulate data as you choose and automate the system with other devices.
I personally don’t use this myself at all, so it would be a little pointless me trying to explain it HOWEVER the community has provided documentation to do so which I’ll link to:
Node-RED Installations Instructions
Node-RED Givenergy API Flow Instructions
If I find time I’ll try and put a bit more effort in on this but as it stands the above links should suffice to get you going.
