The Smallest WiFi Button in the World (ESP8266, MQTT, IFTTT)

6 років тому

This tutorial is showing how to built a small WiFi/Dash button for an ESP-01 module. A button and a LiPo Battery is added. The case is 3D printed. The software is based on Mongoose OS and sends notifications to an MQTT server and IFTTT over a direct web link. The video is also showing a possible use case for such a button.. enjoy watching.
The code can be found here:

Inefficient, imo. You went for full software, but with a simple, tiny MOSFET or transistor of any kind, you could increase the battery life massively. Instead of going for deep sleep, make the pushbutton actually supply voltage to the ESP; once the esp boots up, make it latch the power supply for itself, do the WiFi stuff, and then unlatch the power supply (simple GPIO set/reset) - battery is not connected anymore, 0 power drawn. No need for deep sleep here, as it doesn't have to wake up on its' own.

His goal was to minimise added hardware, I think. A month of battery life is good enouhgh.

This is nice - especially the cat feeder! :) I did something similar, albeit larger, to control Hue lights using a Wemos D1. To get the required latency I went for static IP addresses, so no waiting on DHCP. Works great in a home environment. Didn't use MQTT or anything - just straight API calls to the Hue bridge.

Hi, well done in this video! I've just a question. With this circuitry and Mongoose OS, could I make a button that turns off or on my Yeelights using LAN Control Protocol, without needing other devices, or also trigger IFTTT commands? LAN Control protocol enables prompt commands that you can trigger from the LAN network.

Very inspirational! Your MEGA LED matrix got me hooked onto the journey of ESP32 and ESP8266. Have ordered a couple of components to get the LED matrix going. I'm conceptualising a few more projects and one thing that happens often is missing to lock the sliding windows. Here's the question: Taking the cue from the smallest Wifi switch in the world do you think it would be possible (or maybe you've done it already) to incorporate one part of a hall sensor into the casing housing the ESP which then registers a "closed" event when the lever of the window lock is in the locked position? In other words this setup checks for the lock in the locked position rather than the window/door shut - well I could possibly monitor both window shut and locked :)

Hello Master, I like watching your video very much. I learned a lot from it. I have a question. The ESP-01 voltage is 3.3V. The full voltage of the lithium battery may reach 4.2V, which will cause this circuit. Influence?

So cool to see you using Blender. Love that program. What 3D printer do you use? Thanks for the info. I didn't know the ESP8266 could be programmed this way. Would an FTDI USB to serial work for programming (like the one for programming the atmega328p) ? Thanks!

@darknessblades 5 років тому

this is something i plan on creating. only then to controll a smart home. 1 main controller with multiple override buttons 1 timer switch that is send a command to the slaves to run the program at a set time. for example run program X1 at time 12:00 run program X2 at time 18:00 run program X3 at 19:00 run program at: 20:00 it needs a screen so you can easily set up times for each day of the week. {time setting will be in intervals of 15 minutes} with multiple settings like override program till time X. for example normally monday you have 2 4 programs, like on off on off (so it is on when you are at home but off when you are gone) but if you are at home on that day the override programming will keep the program for that day till X? {something like a holiday button for a smart thermostat}

Is the connector for the battery charger just hooked up in parallel with the rest of the circuit? Can you charge the battery while the battery is still connected to the ESP provided that the ESP is in deep sleep? What happens if it's not in deep sleep? i.e. What happens if someone presses the button while it's charging?

@mstylesms 6 років тому

Very nice! A quick question for you. Can this be written or wired so that it detects when a door opens or closes? Think of a garage door that may stay open or closed a long time and using a coin cell battery. Is this possible?

@onshisan 6 років тому

I don't think a 3V coin cell is necessarily appropriate, but conceptually the push-button switch could be replaced by a different sensor. For a door, which is necessarily not moving around, using a larger battery (or accessing mains power with an adaptor) would give considerable flexibility. But as mentioned elsewhere here, it would likely consume less power to have the sensor send a signal by some other, lower-power radio technology than WiFi to a bridge or hub... lots of ways to approach this problem :)

@RupinChheda 6 років тому

I am kind of confused. Firstly, can you run the esp from a >3.3V power source? And how is the reset kept pulled high with just the push button? Won't it go back to being low once you remove the finger? Or is it a two position switch?

@triularity 6 років тому

He did say "do so at your own risk" using a direct 4.2v battery.

@gmiller123456 6 років тому

Those are 3.7v batteries, and in my testing with a benchtop power supply 3.7 is the cuttoff where they stop working. Works fine at 3.6v, 3.7v it hangs. It's possible these small batteries can't deliver enough current to keep the voltage above 3.6, or aren't fully charged.

@casemodder89 6 років тому

Just make use of these LiFePo4 batterys ! 2,8-3,65volt and even easier to charge/trickle charged for ages without degradation of capacity.

@jayare7750 5 років тому

using the ESP-01, do you have a code that would help me set up a door sensor with a magnetic reed switch? I would like it to have a status, open alert and closed alert. I don't even need deep sleep as having it on all year is less than $2 a year.

@doro516 4 роки тому

to save battery you shouldn,t use the RST pin, instead of that, yu should use the button to feed source power to the VCC pin, thus the mini board Will be on only when your press the button.

How about a BT version? Sends a BT low power signal a few times when the button is pressed. Set up a phone to search for low power BT signals and start assistant when it finds one. I have have a Chinese BT button but the thing needs constant connection for the phone lost features. And it can't be disable. That keeps the phone awake what drains the battery.
