Ways to make an AND node with true and false output?

Third party integrations Node-RED

Hi everyone, I’m trying to create a sequence that reacts based on multiple device states. This led me to install the node-red-contrib-bool-gate node, which triggers only if multiple conditions are met. So far so good.

The thing here is that this node only has one output and it only reacts when it turns “TRUE”, but when it becomes FALSE (it shows a red dot and says FALSE) it doesn’t do anything. Can anyone recommend another way around this? Or am I missing something?

Thanks,
Rodrigo

Try to use this instead of the and-gate node.

[{"id":"d7fbda01ca7d258b","type":"function","z":"fbef87b08305041b","name":"function 3","func":"if (global.get('homeassistant').homeAssistant.states[\"light.feet_light\"].state==\"off\") {\n    msg.payload=\"false\";\n    return msg;\n}\nif (global.get('homeassistant').homeAssistant.states[\"light.tv_light\"].state == \"off\") {\n    msg.payload = \"false\";\n    return msg;\n}\nif (global.get('homeassistant').homeAssistant.states[\"light.door\"].state == \"off\") {\n    msg.payload = \"false\";\n    return msg;\n}\nmsg.payload=\"true\";\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[],"x":525,"y":360,"wires":[["68b538d379feccd6"]]}]

Ok @WallyR, thanks for writing that code! It’s working, I see that it outputs true or false. I’ll probably use this.

I still wonder, is there any other way to get something like this but without needing to use a function node? I’m migrating from Webcore and even though I love that NodeRED seems to be more graphic, I’m finding that it needs more coding than I expected :s

Thanks,
Rodrigo

You could do the same with a chain of current state nodes.
