    Nice stacked bar charts

    #TIL: stacked bar charts in #homeassistant I wanted nice stacked charts to show my energy consumption in Home Assistant. After combining #apexchart code from several sources (1), the result looks like this: The code: I’ve inserted ‘manual card‘ to the dashboardand inserted the yaml code: Before using Apex charts in Home Assistant, install them via…

  • Proxmox server temperature tracking in Home Assistant

    Proxmox server temperature tracking in Home Assistant

    (Link to the original blog post with a proper layout) It’s a pity that #Proxmox doesn’t report CPU and other temperatures to #homeassistant. I had several freezes of my old laptop that runs Proxmox due to a stuck CPU fan. I googled a bit and found an elegant solution for temperature reporting: a command_line sensor.…

  • How I killed e-ink display

    How I killed e-ink display

    TL:DR: I don’t know how, but it no longer works. In the previous post, I shared the joy of making #ESP32 #Lilygo T5 2.13′ e-ink display finally work and show some sensor data from #homeassistant. The joy lasted only a week. Yesterday I decided I’d print a nice case for it. I found a great…

  • E-ink display showing temperatures from Home Assistant

    E-ink display showing temperatures from Home Assistant

    I had this #esp32 #lilygo board* laying in the drawer for more than 2 years. I tried several times to make the e-ink display work without success.Today I flashed it again with the latest #esphome firmware, stole some code from the web, tinkered for 2 hrs with #yaml and lambdas and whatnot and suddenly… it’s…

  • How to make Fire HD tablet talk in Home Assistant

    How to make Fire HD tablet talk in Home Assistant

    If you have Amazon’s #FireHD (or any other #Android) tablet that shows your #homeassistant dashboard, you can make it talk. I created a new automation (triggered by a motion sensor) which greets me when I approach the tablet: I used the ‘Send notification’ action, chose the tablet and inserted ‘TTS‘ in the message field. Then…

  • Home Assistant and nice statistics graphs

    Home Assistant and nice statistics graphs

    One of the things that bothered me in #homeassistant for more than a year was the following: I couldn’t figure out why some entities/sensors can draw nice longterm statistics graphs like this (with average, max, min values): and some show only bulky history charts (10 days of data) like this: #til Today I learned I…

  • Detecting movement in Home Assistant using Ikea Vallhorn sensor

    Detecting movement in Home Assistant using Ikea Vallhorn sensor

    I’ve bought some #Ikea #Vallhorn motion sensors for 8€ a piece. (see info here) Pairing to the #Zigbee network in #HomeAssistant and #Zigbee2MQTT was somehow difficult, which is not usual for Zigbee devices (at least according to my limited experiences with them). Nevertheless, I succeeded in pairing them. Unsuccessful attempts Firstly I tried to pair…

  • Simple tablet charge controller using Sonoff’s ZBMini

    Simple tablet charge controller using Sonoff’s ZBMini

    I’m using an Amazon #FireHD tablet stuck to my fridge with several magnets and 3D printed case as a #homeassistant dashboard. I read it’s bad for the tablet’s battery if it’s constantly plugged into a charger. Battery can swallow or worse. So I installed Sonoff’s #ZBMini (Zigbee) smart switch into a socket where the charger…

  • When did I change the batteries in my sensors?

    When did I change the batteries in my sensors?

    Last month I learned about the integration which helps track battery change status in various devices connected to #homeassistant. Today I finally had some time to install #HACS integration (source) called ‘Battery Notes‘ which was written by Andrew. After the installation and HA restart, it automatically found my #Aqara battery devices (#Zigbee buttons, magnetic door…

  • Home Assistant and breaking changes (27. 12. 2023)

    I’ve been running #homeassistant for 2 years now and have never dealt with breaking changes. Until today. 1st breaking change: #ESPHome entities are unavailable After updating Home Assistant Core to 2023.12.4 and ESPHome to the latest (Dec. 2023) I’ve noticed ESP entities marked as ‘Unavailable‘. Moreover, all entities had duplicates in the entity list ending…
