Intelligent Immersion solar power diverter and energy monitor

Feature Requests

I’d like to integrate this solar diverter. The device (details at https://www.intelligent-immersion.co.uk/) can be accessed using HTTP and returns an XML document. http://ip.address/ii3.xml returns something like

To make changes pass parameters via GET ie of the form //ii3.local/ii3.xml?xx=a&amp;yy=b&amp;zz=c

parameters currently available
Parameter xx a
override switch sw 0 = local 1 = off 2 = auto 3 = on
relay mode rm 0 = local 224 = none 192 = second load proportional 160 = second load switched 96 = circulation pump
relay rl 0 = off 1 = on
note the relay mode must be set to 224 ie none before the relay will operate.

I am now reading the device successfully using the REST integration. I have not yet looked at issuing commands to it.

Hi HAC S-bank,

I also have one of these units and I am interested in how you did this? I am a bit new to HA and Rest. I think I have something that might work but although it checks out config wise I don’t get any sensors from it.

Here is my REST sensor definition, which I made by editing the XML response from accessing the unit with a browser.
I put it in a separate file and used “include” in the main configuration file.
