Americans have a habit of giving projects names, This Project is Called, Art
Art Thermostat The Art of temperature controlled
Art a better NEST
Art is Smart
Art OpenSource ESP32 Smart Thermostat
Art is TrustWorthy
Internet Safety, You can View & Control whats going on
Because Art is OpenSource
Thermostat via a Google server ???
Switching a light via a Chinese server ???
Hey Google!, Does a NEST Run on LAN Local Network Only?
ESP32 38-Pin = +/- 3 U$ Dollar
SPI TFT Touch Display = +/- 6 U$ Dollar
DS3231 RTC Module = +/- 1 U$ Dollar
BME280 Module = +/- 2 U$ Dollar
(Dual) Relais Module = +/- 1 U$ Dollar
DownScale Control Relais Module / PCB, & Jo Less Energy?
GeekCreit, Keyes?, i want a Dual Miniature or SIP Reed relais module?
Or Dual optoisolated Triac / PhotoTriac PCB module (Will MOC3011, MOC3021, AQH3223 do switch 24~VAC?)
Maybe the AQH3223 IC solid state relais, is better, non zerro crosing, so maybe for AC/DC
With screwless terminal connectors for switch side
For Switching 24VAC / 24VDC
I CanNot Solder that Small
So i stick with modules
Modulair Cheap Easy Replaceable Repairable Environmentally Friendly ;-)
Art is now LIVE!!!
Art's Live Video Stream from old HTC One Mini Phone!!!
Some Say Do Not use spaces in WIFI Router Broadcasted SSID wifiname ;-(
Note: ESP32 only works at 2.4Ghz, my ZIGGO.NL wifi router has no Dual mode 2.4 / 5 Ghz option
Wi-Fi: 802.11 b/g/n/e/i (802.11n @ 2.4 GHz up to 150 Mbit/s)
IEEE 802.11 standard security features all supported, including WFA, WPA/WPA2 and WAPI
BUY Art (Still, Just an idea)
All Parts and Soldered Prototype PCB, Ready To Start Art (UnProgrammed!)
4 inch SPI Touch TFT, ESP32-38Pin, BME280, DS3231, Buzzer, 2RelaisPCB, ProtoType PCB.
Sorry, the phone video recording didnt want to zoom in => next time better
Showed a wrong i2c BMP180 sensor , should be i2c BME280 sensor, E type does Humidity
After 20 seconds Art's BUTTons hide
and a barometer+linear scale and humidity+comfort scale apear (i2c BME280)
a Touch on Art's Bottom (screen), will show the thermostat control buttons again
Art has an ip adres from Art's webserver
TFT screen tells the ip adres 192.168.178.27 in this case
hardcoded wifi settings = not so very not nice
better wifimanager first direct-connect with Phone to ESP32 to Easy Enter WiFiRouterName and PassWord
Art's Barometer say's Stormy, That is Bella.
State of Art
The state of the art (sometimes cutting edge or leading edge)
refers to the highest level of general development,
as of a device, technique, or scientific field achieved at a particular time.
The ESP32 is Dual Core, am i using only 1 core?
can i run the webserver on the other core, to make it more responsive
does the other core know the same variables
the size and speed is allready impressive compared to the Uno, Nano, Mega
Espressif is impressive !
2 much for a Lutjebroeker CauliFlower Farmer Programmer, like me
online internet alarmclock
a lot is not working anymore (radiostations not)
like the countdown till next alarm
inspiration came from (dailyalarms.com no longer online)
thats where the 1440 minutes came from 11 years ago
