Pulse Counter Reset and Display Tips in Home Assistant

Hey everyone! I’ve been diving into some smart home automation lately and wanted to share a couple of tips that might help others out there. I recently stumbled upon a neat solution for resetting a pulse counter’s total value, which was a bit of a puzzle at first. Here’s how I tackled it:

If you’re using a pulse counter sensor for something like tracking water flow, you might notice that the total value doesn’t reset when you turn on a valve. This was tripping me up until I figured out a workaround. By adding a lambda function in my automation, I was able to reset both the flow rate and the total water usage whenever the valve opens. Here’s the code snippet that did the trick:

yaml
on_turn_on:

  • switch.turn_on: valve_switch
  • lambda: |
    id(flow_sensor) = 0;
    id(water_total) = 0;

This simple addition ensures that every time the valve opens, the counter starts fresh. It’s been working perfectly for my watering system!

Another thing I wanted to share is how to display specific attributes in Lovelace. I recently came across a thermostat that had a handy “valve_position” attribute, but it wasn’t showing up by default. After a bit of digging, I found out that you can create a custom card to display these hidden gems. Here’s how I did it:

yaml
entities:

  • entity: sensor.thermostat_valve_position
    attribute: valve_position
    name: Valve Position

Now, I’ve got a neat little card showing exactly how open my valves are. It’s super helpful for fine-tuning my heating system!

I hope these little tips help someone else out there. If you’ve got any tricks or hacks you’d like to share, I’d love to hear about them! Happy automating! :slight_smile:
