Washing Completion Notification based on value from Power Monitoring Plug.

HomeAssistantWashingMachine

## Washing Machine Notification
###############################
## Description:
## 1. Based on power monitoring plug (measuring in Watt & Amp)
## 2. State is determined by power monitoring value (further analysis is required; recommended 3 cycle washing)
## 3. Adjust the Watt & Amp value in the template sensor according to your analysis result
## 4. Notification is triggered based on final value (when washing is completed state)
## 5. Weather forecast is using OpenWeatherMap integration. Can also use others.

# Machine condition may varies. My situation here upon washing completion, it didnt give a consistent value, 
# So I had to rely on Idle state (all value become zero) for 2 mins duration and assume that washing is done.
# Adjust the trigger according to your analysis results.
