Dyson Vacuum Charger – Auto On/Off
This automation automatically turns off a smart plug if the power consumption drops below 3 W, and turns it back on after a set time interval, with checks happening every minute.
I created this automation to prevent the vacuum’s battery from being damaged by staying on the charger in the dock indefinitely.
How It Works
- Every minute, the automation checks conditions.
- If the plug is ON and the current consumption < 3 W:
- The plug is turned OFF.
- The current time is stored in
input_datetime.dyson_charger_off_time. - A notification is created to confirm it turned off.
- If the plug is OFF and a certain amount of time has passed since it was last turned off, the plug is turned ON again, and a notification is created to confirm it turned on.
By default, the code below uses 9 days (777,600 seconds) as the interval. To truly make it 4 hours, replace 777600 with 14400 (4 × 3600).
Required Helper
Create an [Input Datetime][1] helper to store the timestamp of when the plug was last turned off:
- Go to Settings → Devices & Services → Helpers → Create Helper.
- Choose Date and/or time.
- Name it (for example) “Dyson Charger Off Time”.
- Select Store time (or Store date/time, either works).
- Make sure it has the Entity ID:
input_datetime.dyson_charger_off_time.
