Flip-Flop node?

Third party integrations Node-RED

Hi all,

is there a way to implement a flip-flop without using a function node and without using two delay nodes?

I have been told it can be done with a single trigger node but can't see how?

The logic will be:

msg arrives - send "on", wait 5 mins, send "off", wait 5 mins, rinse/repeat until "reset" is received.

Any ideas?

Thanks in advance

Is this a switch or a light? Those domains have a toggle action. You could use a loop timer node to fire every 5 min to a toggle action node. The loop timer node can be reset with a message to stop it.

Thanks, its for an irrigation setup.

That still uses two nodes - the same as my current one with two delay nodes in a loop, one fires on the other fires off, it works ok but was trying to grasp a way to do it with just one node

The only way to do everything in one node would be with a function. Even then a function cannot directly run an action. You would need to interact with the api, which can be done in a function I believe but it's a convoluted way of doing things.
