My MQTT server also has some basic systems management capabilities - means the MQTT server can emit the following data to the MQTT broker:

Since the beginning of my home automation project I made several tests to choose the right platform and right controller. I've done test with various sensor technologies etc. etc.
Most of the articels can be found in the Arduino category.

One decision was, that my webhost should be the main datastore for all data measured. With this decision, I've started to build a data collection and distribution infrastructure. The complete setup consists of two major components:

These components are detailed further down the page.

Here I've build an audio CW-filter based on the circuit from NM0S/4SQRP.

This filter works pretty well. I've done some audio analysis using a cheap soundcard from BEHRINGER and the shareware application AUDIOTESTER.

Now I've finished the Audio CW-filter I've decribed here in details.

Basics

Inspired from the work of EA4TX and K3NG I decided to check, whether the ESP8266 based NodeMCU 1.0 (ESP-12E) is usable as a simple remote IP-based rotator control. You can get the NodeMCU in a decent quality on eBay.

Idea was, to link a local emulated serial port to the NodeMCU module. The HAM Radio applications are communicating via the standard Yaesu GS232A protocol with the emulated serial port.  This emulated serial port then forwards the serial requests to the NodeMCU.
