One way would be to have the html elements in a <form> element with a submit-Tag which has the address of the pyboard in it. Whenever you submit the form the values of the variables will be submitted with it, either in the url (method=get) or in the body (method=post) of the request. A little bit mo...

Just a small hint: They cut the cost wherever possible and one thing I noticed that the detection switch for the SD Card is not there. So no Auto-Mounting of an sd card for you. I also assume that all the other components will be as cheap as possible, which surely does mean more energy consumption a...

Thanks for your great tutorial, and I don't want to smaller your achievement in any way. But am I the only one whose toe nails curl simply by reading "IFTTT"? Everyone relys on an opague online service, sometimes giving them passwords so that they can control devices in my home, without really under...

Seems easy enough to do it directly in Micropython without a (C) driver. Just try it!

Hi ghayne, I've done the very same thing (without using MQTT, that is) and here is the code: https://github.com/ThomasChr/ESP8266-read-power-meter/blob/master/main.py Works since a few months now and only resets/crashes about all two months. So pretty stable. Just try out if your problem vanishes wh...

Simply use one of your favorite buses to communicate between Arduino and Pyboard, those are: SPI, I2C or UART All differ in functionality and speed. So you need to have your requirements in mind. And when you got the data it's your decision how to save it. On an ESP8266 sending the data over WiFi co...

Afaik are timers (like nearly everything else) not retained through a hard reset. Why should they?
A hard reset is like pulling the plug. Almost everything except flash content and (if a battery is attached) the RTC is gone then.

Maybe it‘s time to put the Logic Analyser into good use. You can get one for up to 10 MHz in China (salea logic clone) for a few bucks.
It can tell you exactly what voltages/commands the LEDs see.

I think this is one of the smallest formfactors for the ESP32: Directly the module WROVER from Espressif! https://www.aliexpress.com/item/33006996531.html Bonus: It's got 4 MB of PSRAM. Thats a lot of memory for micropython. On the negative side: It needs a regulated power source of about 3 / 3.3 Vo...

Jep, get an ESP Module with more Pins. ESP32 modules are not expensive!
