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?
