The new Opportunity Loads feature in 3.80 is very beneficial.
Am looking for a solution to turn on the spare relay 2 in Ekrano GX to activate a DC load when excess solar power is available.
e.g. Is there a way to trigger Ekrano Relay 2 to ON when excess solar power is available?
(12V DC system with a Multiplus 12|1200|50, Ekrano GX).
Yes, use the new S2 nodered module (resource node)and send the ombc control signal to the relay (using a suitable function or node to convert the payload to the right format).
I do this currently with a virtual switch but it could be any switching device or relay.
Thanks @Nick - that will get me started. Do I need to have a power-meter device or can I fake that (known load)?
Fake it til you make it 
Going to shuffle this to nodered land.
There are examples included with the S2 resource node for guidance. This is a screenshot of mine showing the interactions, functions are pretty much just checking for bad data and converting the source into a payload the target node expects.
In my case I am using a Tuya device for data and the target of a virtual switch.
The resource node needs to be sent the device power and and a state acknowledgement when it requests and on/off - though you can skip this and enable a default, automatic ack in the resource node control itself.
You have to see, how that goes. Depending on the load size and available solar it will for sure start at one point, but internal maths won’t really work out, as OL currently only supports ACLoads, as the underlying S2 Standard only supports that by now.
(Our CR to add a Commodity DC is already submitted )
