ESPHome-Devices

A collection of my ESPHome configuration files and code for my various ESP8266 devices that integrate with Home Assistant.

ESPHome

ESPHome is a system to control your ESP8266/ESP32 by simple yet powerful configuration files and control them remotely through Home Automation systems. For more information checkout ESPHome.io.

Home Assistant

Home Assistant is open source home automation that puts local control and privacy first. Powered by a worldwide community of tinkerers and DIY enthusiasts. Perfect to run on a Raspberry Pi or a local server. For more information check out Home-Assistant.io

Coffee Maker

This is a NodeMCU that I installed in my Cuisinart Coffee Maker. It has GPIO's connected to the indicator lights for the bold setting and power and has a couple of relays connected to the bold setting button and the power button. Aside from the ability to trigger automations based on the state of the coffee maker and automate turning on the coffee maker I also added a "bloom" feature. Coffee tastes better if you let the carbon dioxide escape (bloom) after getting the coffee grounds wet before continuing the brew cycle.

Feit Dimmers

I have a couple of Feit Dimmers (Kitchen Table and Office) I bought as a 2 pack at Costco. This is a pretty basic config that replaces the original firmware. I re-flashed these using Tuya-Convert.

Fire Pit and Fountain

This is a WEMOS D1 Mini Pro that is connected to a couple of relays and a couple of water proof push buttons red and blue. The multi-click config on the fire pit switch is so that any press will turn it off but to turn it on you have to press it for 5 seconds (to try and prevent kids from turning it on). This will be used to control my combination fire pit and fountain in my backyard when I am done rebuilding it. I have done some testing at my desk but this is not fully hooked up yet so there may be some bugs (winter came to fast).

Garage Fridge

This is a NodeMCU that I have installed in the back of my garage fridge and is connected to several temperature sensors that monitor the temperature of the compressor, the fridge, and the freezer and a pair of relays that control a heat tape wrapped around the compressor and a couple of heaters that are inside the fridge. This is to prevent the compressor from getting to cold (when it is cold the oil thickens up which is hard on the compressor), the fridge from dropping below freezing (frozen beer is no fun), and the freezer from getting to warm (when temperatures in the garage are around the desired fridge temperature the freezer tends to get to warm because of lack of cooling demand from the fridge so we warm the fridge up a little to get it to kick in the compressor).

Master Bed

This is a NodeMCU that I have installed under my bed and is connected to a pair of Force Sensitive Resistors that are placed between the mattress and box spring of my bed, one for my side and one for my wife's side. Because the ESP8266 has only one analog input I had to add some transistors connected to pins D0 and D1 that are used to select which FSR is connected to the A0 analog input. The custom binary sensors in bed_sensor.h handles switching between the FSR's and calculating who is in bed. Generally when the bed is empty the reading is the full 1024 (or at least close to this). If someone is on one side of the bed or the other the reading is typically around 100. However if you lay in the middle of the bed I tend to get readings of around 600-700 on both sides. Thus the 3 different binary sensors (Chris is in Bed, Melissa is in Bed, Someone is in Bed). There is also a Master Bed Count that reports the total number of people in bed, I compare this to a sensor in Home Assistant that tracks the number of "masters" (my wife and me) that are home so that I can activate night mode when everyone is in bed.

Patio Lights

This is a WEMOS D1 Mini Pro that is connected to a relay to control the power to the landscape lights around my patio. I used the WEMOS D1 Mini Pro because it has an external antenna. I initially used a WEMOS D1 Mini clone but the power supply for my lights was to far from the house and I kept having connectivity issues.
