# Laundry Finished Notification

**[apalrd's adventures](https://daily.dev/sources/apalrd)** · 3 min read · 0 upvotes · 0 comments

## Summary

A practical Home Assistant automation that sends phone notifications when the washer or dryer finishes a cycle. The setup uses two Sonoff S31 smart plugs flashed with Tasmota for power monitoring, with carefully tuned power thresholds (5W for 2-5 minutes for the washer, 10W for 1 minute for the dryer) to distinguish standby from active cycles. The YAML automation passes a configurable trigger ID as the notification message and supports targeting specific devices.

## Questions this post answers

### What power threshold should I use in Home Assistant to detect when my washing machine has finished its cycle?

A threshold of 5W with a minimum duration of 2 to 5 minutes works well for a washing machine. The washer's water valve draws around 8W and control electronics draw about 2W at standby, so 5W sits safely between true standby and the low-power fill/rinse phases, avoiding false triggers during quiet parts of the cycle.
