ESPHome-Devices

Overview

This is a collection of ESPHome custom components, configuration files, and custom code for my various ESP8266/ESP32 devices that integrate with Home Assistant. I am using includes and packages pretty extensively in order to prevent duplication and allow for easy changing of common settings.

What is 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.

What is 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.

Secrets Management

You will notice that throughout the various folders I have secrets.yaml files. These files all do an include of the secrets.yaml file in the root folder (that for obvious reasons is not included in the repo). On my computer the secrets.yaml file in the root folder is a symlink to a file in my OneDrive folder. This way I have multiple backups of this file and don't have to worry about losing it and getting locked out of all my devices.

Custom Components

I have been working on updating most of my custom code into components that can easily be pulled directly from GitHub into your device configuration using the external components component. I have run into frequent issues with changes in ESPHome breaking my components so I am now tagging my repo with the version of ESPHome it is compatible with. I generally upgrade pretty quickly so as soon as I have confirmed things are working and/or made the neccessary changes I will add a tag for the new version of ESPHome. While I primarily design these components for my own personal use cases I hope that at least some of them are useful for others. If you are using one of my components and have an enhancement/feature you would like to see feel free to add an issue and I will see what I can do to get it added.

Binary Light With Power

This an enhanced version of the standard binary light component that adds an option to include a sensor to report current power usage based on a configured wattage of the light(s) it controls. More details on how to use this component are available here.

GPIO Light With Power

This an enhanced version of the standard gpio switch component that adds an option to include a sensor to report current power usage based on a configured wattage of the device(s) it controls. More details on how to use this component are available here.

Pool Controller

This is component is curently running on a Shelly 2.5 Double Relay Switch and is used to control the main pump and the auxiliary pump (that runs a pool cleaner) on my pool. Eventually I want to expand this to run on an ESP32 and manage all aspects of my pool (pumps, lights, heat, fill, drain, pH, ORP, etc.). More details on how to use this component are available here.

TREO LED Pool Light

This is a custom light component that works with TREO LED Pool Lights and exposes the different colors as "effects" so thay can be selected from Home Assistant. More details on how to use this component are available here.

Tuya Dimmer as Fan

This a modified version of the Tuya fan component I use with Feit Dimmers (but it will likely work with other Tuya dimmers) to control bathroom fans and adds several features. I created this component because I couldn't find a regular on/off switch with the same look and feel as the Feit dimmers so I decided to use the Feit dimmers but use this component to prevent "dimming" the fan. More details on features and how to use this component are available here.

Tuya Light Plus

This an enhanced version of the standard Tuya light component that adds a bunch of extra features. I use this component with Feit Dimmers but it will likely work with other Tuya dimmers. More details on features and how to use this component are available here.

ESPSense

This excellent component is not mine and doesn't live in this repository but most of my devices are using it so I felt it was worthy of a mention here. More details are available here.

Misc Devices

Basement Bathroom Sensor

This is a WEMOS D1 Mini clone that is connected to a motion sensor, a temperature/humidity/pressure sensor, and a door sensor and is used to control the lights, fan, and heater (heat lamps in the fan) in my basement bathroom.

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.

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 3 seconds (to try and prevent kids from turning it on). This is used to control the combination fire pit and fountain in my backyard. I just got this hooked up and is working good other then the fire pit doesn't always come on on the first try (I think I am getting some bounce in the switch but haven't had a chance to troubleshoot further).

Garage Fridge

This is a M5Stack ATOM HUB SwitchD mounted in a box on the side of my garage fridge with a PZEM-004T. It is paired with 2 Inkbird IBS-TH1 sensors for monitoring the temperature in the fridge and freezer sections. One of the relays on the M5Stack ATOM HUB SwitchD is used to control a pair of heaters that are inside the fridge to keep the fridge from dropping below freezing (frozen beer is no fun). I am not entirely happy with the parameters for the PID controller, I would like it to reach an equlibrium where the heater is on just enough to maintain the temperature at all times but instead it tends to ramp up and down quite a bit. The good news is even with the varying heat output it keeps the temperature pretty close to the desired temp. Using the autotune feature doesn't work because the bluetooth seems to cause periodic reboots which resets the autotune process. Maybe next winter I will try to create a temporary custom autotune that can survive restarts.

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 sensors in bed_sensor.h handles switching between the FSR's and reading the values from the FSR's. 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.

Pool Pumps

This is a Shelly 2.5 Double Relay Switch that is controlling the main pump on my pool and the auxillary pump that runs the pool cleaner via my custom Pool Controller Component.

Scripture of the Day Melissa/Scripture of the Day Mayson

This project was one of the first projects I have done that I would call woodworking. I made 2 of these as Christmas presents for my wife and son. They consist of an ESP32 e-Paper Panel Driver Board powered by a lithium battery and TP4056 lithium battery charger module and driving a Waveshare 7.5inch 800×480 E-Ink display. The ESP32 sits in deep-sleep most of the time but wakes up every night, grabs a random scripture from the Our Manna Daily Verses API, updates the display with the verse, and goes back to sleep.

Switches

I plan to use dimmer switches for anything that is dimmable just for consistency and you never know when you might want to have the ability to dim a light. However there are times when a dimmer isn't an option.

SANA Dual Switch

My basement bathroom has 4 devices (main light, fan, shower light, and heat lamps) but only 2 single gang boxes (and not enough room to swith to dual gang) so these were a perfect fit. The price is right, the buttons feel solid, and I was able to flash them using Tuya-Convert. They do seem to have corners that are squarer then typical so I had a little bit of trouble getting a standard cover to fit but nothing I couldn't fix with a file.

• Basement Bathroom Shower Light and Heater

SANA Triple Switch

This is installed in place of the switch that controled my TREO LED Pool Lights. These lights have the option to select different colors by briefly turning them off and back on again and they do remember the last color when turned on again. The custom TreoLedPoolLight.h component handles tracking the current color and exposes custom "effects" for each of the colors to Home Assistant. I went with the triple switch so that I could use the third button to control my Patio Lights which otherwise do not have a physical switch. The one issue I am having with this is occasionally the "effect" on the switch gets out of sync with the actual color of the lights. It has only happened a couple of times so I haven't gotten around to investigating why it happens.

Dimmer Switches

Feit Dimmers

After trying several dimmers I finally decided to standardize on the Feit dimmers.
Things I like about these dimmers:

• Can be flashed using Tuya-Convert Unfortunately Feit has started shipping these with updated firmware that does not currently work with Tuya Convert. Hopefully the excellent Tuya Convert team can figure out how to work around the new firmware. Until then I did find this tutorial on flashing these devices (I have not tried this yet).
• Have a solid feel to them
• They can be linked via a traveler wire (this works even when flashed with ESPHome and while not mentioned in the documentation you can link more than 2 switches this way)
• Are readily available from Amazon or Costco for an affordable price.

Things I don't like about these dimmers:

• Have to click repeatedly to change the brightness (can't hold to change)
• All buttons are managed by the Tuya MCU so adding things like double-taps is kind of a hack

All of my dimmers are using my custom Tuya Light Plus component.

Dimmer Switches as On/Off Fan Switches

Feit Dimmers

I tried to find an on/off switch that looked/felt like the Feit dimmers to use for controlling bathroom fans but didn't find anything so I decided to use the Feit dimmers. I don't want the fans "dimmable" so I created a custom Tuya Dimmer as Fan component that changes the "brightness" back to the maximum value if changed at the switch.
