Trafasi TNG

1st_readme.md

Renewed approach to the washer and dryer monitor I'm using. This incarnation replaces the old one found here.

Disclaimer

This is not a plug and play project. I build this a tuned it for my specific setup. Your washer and drying will very likely behave differently so you will have to tune specifics, thresholds etc. Also: I didn't bother calibrating the power usage as I'm only interested in "Is the device currently running or not?".

Requirements

• Home Assistant
• ESPHome
• 2 Wemon D1 mini or similar
• An ADS1115 board
• Two current clamps like the SCT-013-000
• Two USB power adapters with a micro usb connector cable to power the D1s.
• One Wemos RGB Shield
• Optionally: a DHT sensor to measure the temperature.
• Optionally: a case for the alerting device. I found this one
• Optionally: A generic water proof case for electrical devices.
