Home automation, monitoring and control requires a user interface that is easy to use. There are numerous commercial solutions for this.
If you have high requirements for data security and privacy, a self-hosted smart home solution is the way to go. I tried a few open-source solutions and ended up happy with “Home Assistant”. In this post I want to explain how to get a minimal instance of Home Assistant, MQTT, Certbot and Nginx Proxy up and running with Docker Compose.
I’ve been interested in having my own solar panels on the balcony for a while. I have so much unused space. Due to the energy crisis, bureaucratic hurdles in Germany for balcony power plants were removed. The stars were right and I took this opportunity to become a little more self-sufficient.
The Internet of Things is a term for objects, sensors, “things” that sit around somewhere and send data to a network to build applications or business models with that data.
The LoRa network and LoRaWAN as a protocol is a very exciting technology that promises to send sensor data over an energy-efficient wireless network. “LoRa Gateways” are used to receive these signals. The gateway has access to the Internet and persists this data in an application server of a LoRaWan network. “The Things Network” (TTN) is an open LoRaWan network where anyone can provide their gateway and where anyone can connect their sensors with existing gateways around the world. Also there is “The People’s Network” with which you can even earn passive income as a gateway operator. I recently purchased several LoRa modules and a gateway. In this article I would like to discuss the different aspects of LoRa and evaluate it in the context of my battery powered interet devices.
We recently had a hot water bottle, which no longer served it’s duty. How can a hot water bottle can no longer work? The seal on the cap wears out. The hot water bottle drips when you fill it with water.
Another small plastic part, which leads to the unusability of the whole object. For us, an object does not end up in the trash because of such small parts. It’s time to get down to business.
It’s time to permanently look for alternatives. I would like to present a few good alternatives that are currently in stock and are at least as good (or even better) than their Raspberry Pi or Arduino counterparts. Watch the video here.
Everyone has some things lying around in the kitchen. In our kitchen, these are things like rolls of garbage bags, rolls of aluminum foil, towels or cooking spoons.
This needs a solution to organize the items. I built a modular design, which provides a solution for all this. This solution can be attached to the wall, but also via modules to any furniture such as Ikea kitchen frames. This is the first product from my local-manufacturing venture. In this blogpost I want to introduce this solution. The Modular Kitchen Organizer can be downloaded on Thingiverse. Here is my Youtube video about this project.
