Influxdb on Technical Notes

Home Assistant on a NUC

Wed, 12 Oct 2022 00:00:00 +0000

Installation of Home Assistant OS (HAOS) on an Intel NUC5i5RYK — a very powerful machine for this task, but I had it available and wanted to make use of it. I started by setting it up on a Raspberry Pi4B, moved to a virtual machine (with considerably better performance) on KVM, and in this post I describe how I did the installation on a NUC.

Connecting HASS with Node-RED

Sun, 02 Oct 2022 00:00:00 +0000

I explain how I connected Node-RED with my Home Assistant (HASS), considering that they run on separate servers. They are deployed on different virtual machines, to allow independent maintenance and improve their performance.

For your reference, I created another post here where I describe the Node-RED installation using Alpine and Docker underneath, running as a virtual machine on my KVM server.

Node-RED on Docker

Node-RED is a programming tool that allows you to connect hardware devices, APIs, and cloud services through creative workflows. Everything is done from the browser, and it supports dozens of built-in and third-party nodes.

Here I’ll explain the installation process, on a virtual machine with Alpine and Docker underneath. If you’re interested, I have another post describing how I integrate it with my Home Assistant.

Home Assistant SolaX

I describe how I integrated my photovoltaic installation into Home Assistant, featuring Axitec panels, a SolaX Inverter, and a pair of Triple Power batteries. After trying several options, I settled on the MODBUS/TCP integration which works locally via LAN and exposes more data than the other options.

Grafana, InfluxDB and Telegraf Server

Sun, 06 Feb 2022 00:00:00 +0000

I set up these three services on a dedicated server at home to monitor my home automation. InfluxDB is a database super-optimized for working with time series. Grafana lets you create dashboards and graphs from multiple sources, and Telegraf is a lightweight agent that collects, processes, and sends data to our database.

I’ve decided to install all three on an Ubuntu 20.04 LTS server, on a virtual machine in KVM, so they’re consumed by the rest of the home automation elements: the Home Assistant server and other devices that can write to InfluxDB.

HASS migrate Grafana and InfluxDB

Sun, 06 Feb 2022 00:00:00 +0000

I’ve migrated the InfluxDB/Grafana services from my Home Assistant to an external server. Moving the service and setting it up on another server isn’t too difficult. What did take me a while was figuring out how to export and import data between the InfluxDB instances and how to adapt the old Grafana Dashboard to use Flux.
