[OpenBeken] Implementing a Timer to Auto-Off Relay Below 10w for 10mins Like Tasmotas Rules

How to add a timer that turns off the relay when the power is below 10W for 10 minutes.

So basically the same you can do in Tasmota with these commands:

please provide code examples and how to add them.

Hello user4318435,

Certainly, you can achieve this with a microcontroller like Arduino and a power monitoring sensor like ACS712. I'll try to provide a basic code snippet and schematic that you can use as a starting point.

Here's a simple code example that should work:



This script reads power every second. If power drops below 10W, it starts counting time. If power stays below 10W for 10 minutes, it turns off the relay.

Next, you'll have to connect your ACS712 or similar power sensor to the Arduino and connect the relay to digital pin 8.

Please note that you might need to adjust the `calculatePower` function to correctly calculate the power based on your power sensor's readings.

Is this the kind of solution you were looking for? Also, could you provide more information about your hardware setup? Are you using a dedicated power monitoring sensor, or is this integrated into another device?
