Hello,

I have built yet another watering system which has 4 capacitive moisture sensors, 4 water solenoids, 1 pump, and 5 relays.

Everything's working fine, the "brains" is Node Red and I'm sending the sensor readings and relay "triggers" via MQTT to a ESP32. I now would like to add a timer to each relay channel so I keep the sensor readings, but "block" the MQTT messages to the relays via the timer.

So, the message only gets sent between say 07:00 and 08:00. I've looked into BigTimer but that can only output a msg. I would like to pass on a payload msg. where necessary between the "on" times.

Preferably there could be 2 timers and a UI interface.

Does anyone know such a timer exists or would this need function?

Regards  
Ian

If I'm reading this right, you want to inhibit messages between certain times?

Off the top of my head you could use a function node and return null if the current time is \< 7am or \> 8am otherwise return the msg.

Perhaps the within-time node?

Yes that's correct.

I take it it would be possible to enter the given times through a numeric Ui input?

Plenty of ideas here:

> Hi I am looking for a node that can pass or block depending on the day of week and between two times and if the week is odd or even. A switch Node would work if it had selections for odd or even week numbers and select a time frame for example from 11Am to 1Pm.

Thanks I already have the within time node, I'll try it out.

As with your other suggestion I would still like to have a UI interface for it though.

The within time node works great!
