9 months ago Problem is that you need the 2 inputs at the same time, while Node-RED typically uses a single msg.payload when running. This can be solved by storing the values into context.
Taking a look at this example for inspiration. The new flow looks like this:
The first group stores the current values of the SOC and PV power into a variable. The inject node checks. every 15 minutes if the conditions are met. If so, it steers the relay (which you need to modify to steer the Shelly).
Once you have it deployed, you can check the context menu for the current values:
The full (example) flow becomes:

Hi Dirkjanfaber
I want to know how can I use the "AND" operator in NodeRed to check what my PV Yield is as well as SOC. If my PV is above 4000Watt and my battery is above 40% I want my geyser to switch on via my shelly device. Can you maybe assist me with this? I have tried making a "AND" Javascript in the function Node but It won't work, I don't know how to fix this.
Kind Regards,
