Smart Dryer Voice Notifications - Coming Soon

Image
Electric Dryer Voice Notifications Everyone has been asking how to monitor their electric dryer after the initial Smart Laundry video, well look what the mail service brought today!  The parts!  I'm was too excited to not post this as I get started on documenting the project for everyone.  A huge plus is it should work for all countries as it is non-invasive without any modifications to the dryer itself. The load of the dryer doesn't pass through the unit, it just monitors it.

Parts List so far:

PZEM-004T Ammeter Board (split core models available too)
Standard Sonoff Basic
Jumper Wires
1K Resistor (variety kit linked)

PZEM-004T Ammeter Board
Standard Sonoff Basic
Jumper Wires
1K Resistor (variety pack linked)

And a small enclosure to put the Sonoff Basic, power wire, and the PZEM board in.

There is a minor bit of soldering involved but very similar to the Sonoff S31 flashing process in the Smart Laundry video.  As mentioned in that video its very simple if …

We were doing it live! Catch the Replay of the Full Smart Switch Teardown and a new Dimmer.

Image
Two switches shown in the video:

Martin Jerry Switch
Martin Jerry Dimmer

Did a rather short (sarcasm) live stream showing the process to break open the smart switch, identify features, flash tasmota, setup the template, etc. It was my first time doing this switch model and first time doing the real live stream.

I also showed the bonus of the very cool new dimmer switch I've been working with on and off. It's very close and works out of the box right now as it is with a few Tasmota rules.

Had a lot of fun and let me know if you'd like to see more of these (hopefully shorter next time!)
