Tasmota ist eine kostenfreie alternative Firmware für Geräte die auf dem ESP8266 Chip basieren, das sind solche von Sonoff und vielen weiteren Herstellern. Das Projekt startete offiziell im Januar 2017 von Theo Arends und wurde entwickelt um die Geräte einfach in sämtliche Smarthome Systeme einbinden zu können. Übrigens bedeutet Tasmota Theo-Arends-Sonoff-MQTT-OTA.
Tasmota befreit deine Geräte von undurchsichtiger Software um ihnen zu ermöglichen in Systemen zu funktionieren für die sie nie vorgesehen waren!
Obendrein erlaubt dir das deine Geräte unter einem Dach laufen zu haben und dein Smarthome und Zuhause zu vereinfachen.
NATS Server is a simple, high performance open source messaging system for cloud native applications, IoT messaging, and microservices architectures.
OwnTracks allows you to keep track of your own location. You can build your private location diary or share it with your family and friends. OwnTracks is open-source and uses open protocols for communication so you can be sure your data stays secure and private.
One of the most common questions I’m asked to cover when I discuss software architecture topics is the difference between the various application messaging protocols that exist today—issues like how and why the protocols came about, and which one should be used in a particular application.
My adjustable height desk [1] can now measure it's current height and announce it via MQTT thanks to a little NodeMCU script I whipped up and an HC-SR04 ultrasonic sensor connected to the ESP8266. Using mqttwarn [2] that data gets pushed into a Google Docs spreadsheet where I can then plot it easily.
QTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. For example, it has been used in sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small device scenarios. It is also ideal for mobile applications because of its small size, low power usage, minimised data packets, and efficient distribution of information to one or many receivers
Mosquitto is an open source (BSD licensed) message broker that implements the MQ Telemetry Transport protocol versions 3.1 and 3.1.1. MQTT provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for "machine to machine" messaging such as with low power sensors or mobile devices such as phones, embedded computers or microcontrollers like the Arduino. A good example of this is all of the work that Andy Stanford-Clark (one of the originators of MQTT) has done in home monitoring and automation with his twittering house and twittering ferry. Andy gave a talk on this at OggCamp that explains a bit about MQTT and how he uses it. The slides and audio are available online at slideshare
