Do you use an electric dryer and need a solution to send voice notifications when the cycle is complete?  Let's build a simple non-invasive DIY sensor that monitors the electrical draw from the dryer using a Wemos D1/NodeMCU, a couple resistors, capacitor and a split core current transformer.  You can also apply this same project to many other electrical monitoring projects in the home. 

Parts List
Split Core Current Transformer
Wemos D1 Mini 
10µF Capacitor
10k Resistors 
Preformed Jumpers
Breadboard

The LOHAS LED Bulbs utilize dual channels of warm white and cool white LEDs on the MY9231/MY9291 LED drivers.  We show in ESPHome how to solve this issue with a custom component.  All of the sample configurations used in the video can be found at the GitHub link below.  The Anoop bulb is a dual channel PWM light shown in Tasmota.  We also show how to easily configure the device using the new copy and paste templates of Tasmota.

Renting or can't swap out your light switches with the various solutions we have shown?  Let's check out some smart lighting options.

Lights Used
Smart Bulb RGBW
Smart Downlight RGBW - 4inch
Smart Downlight RGBW - 6inch

How to configure both ESPHome & Tasmota with 2 smart lighting options.  Both of these devices utilize the MY9291 LED Driver inside.  After using the easy Tuya Convert process to flash custom firmware we show how to configure each light in Home Assistant for MQTT/API Local Control without the cloud.

I built another multisensor for the bedroom and I decided to change up a few components.  Dive in and take a step by step approach to build it with Otto Winter's ESPHome software this time around as it's been a year since I built the initial Bruh Automation version.  ESPHome is easy to use and configure; No Arduino IDE, no coding, just a config file and the sensors wired up!

Huge shout out to Bruh Automation for starting me on this ESP8266 journey on the first version of this multisensor a year ago.

Easy setup of wireless sensors utilizing the Sonoff 433mhz RF Bridge.  Custom MQTT topics and automations with Tasmota rules all self contained in the bridge.  We also check out the trigBoard from Kevin Darrah with deep sleep modes and custom sensors all from a battery powered ESP8266 based board.

You heard correctly, flash all of your SmartLife Tuya App devices with no soldering at all.  Flash them while you can before devices are updated.  All you need is a Raspberry Pi 3 to flash your devices with Tasmota.  No soldering at all and you will have full local control unlocking the true power of your smart devices.

UPDATE: Be very careful that you put in the correct SSID and Password.  It might not be a bad idea to put in a simple backup SSID and Password in position 2.  If for some reason you mistype the slot 1 password you could always change your WiFi router to send out the simple SSID and password in slot 2 to fix the issue with slot 1.  Also once you get into the switch/plug Tasmota GUI, I would highly recommend changing the WiFi Config tool to WiFi Manager by typing "wificonfig 2" (without the quotes on the console), it should respond back with that WiFiManager is selected.  This will make the device go into access point mode anytime there is an issue with connecting to the wifi.
