Introduction In this tutorial, we’ll show you how to send data from cheap WiFi nodes to a Raspberry Pi over an internal WiFi network. It relies on the Flask framework for Python, which is a relatively simple-to-use method of creating a web application that can execute Python scripts. We’ll use a Raspberry Pi 3 and SparkFun ESP8266 Thing to […]

I have always been monitoring my utility meters in the old fashioned way. First I wrote them down in a little ledger (yep, I’m that old), later I wrote a spreadsheet for it and the last few years I’m using the ECAS smartphone app to do the trick. I always wanted a live monitor, but

After we managed to connect the ESP8266 WiFI module to Raspberry Pi, we can now try to change the module firmware to a custom one. The firmware we will install on it is a simple webserver, that will handle HTTP requests. It will allow us to access a web interface for ESP8266. The interface will

ESP8266 boards are pretty neat, but if you just bought one (And why wouldn’t you for only $5?) and have realized that you don’t have any obvious means (3.3V TTL USB serial device) to communicate with it, you can talk to it directly with a Raspberry Pi. Both use 3.3V signaling, so no level converting
