Laundry Finished Notifier

This small project shows how to turn a "dumb" washing machine into a somewhat smarter one which is able to notify you via ntfy.sh about the finished laundry and the energy it consumed.

This can be done with a simple smart socket running Tasmota firmware, i.e. without running any MQTT broker or full-fledged home automation system.

Design

The provided rules perform the following steps:

  1. Wait for the current power consumption to rise to StartWatts or higher.
  2. Store the current value of the total measured energy, and send a notification (topic "laundry") about the start of the laundry to the ntfy.sh server.
  3. Wait for the current power consumption to drop to DoneWatts or lower.
  4. Wait for the grace period.
  5. Compute the energy difference and send a notification (topic "laundry") about the end of the laundry to the ntfy.sh server.

If during steps 4 the power rises back to at least StartWatts, the grace period timer is stopped and execution returns to step 3.
