Some interesting tweets by @isotopp and others on home power measurement and what to do to optimise energy usage at home

Posted by jpluimers on 2025/02/26

For my link archive (browse back and forth in the tweets: lots of useful tips):

[Wayback/Archive] Kris on Twitter: “@mausdompteur @HildebrandtRalf … Tasmota Support P1-mqtt in Python, für den oa Zuidwijk Slimme Lezer Diese Lösung setze ich ein.”

Posted by jpluimers on 2025/01/03

Yup, I have been in the Ring ecosystem since way before Amazon took them over, and it is kind of hard to part from the useful cameras, so here is for my link archive: [Wayback/Archive] Latest Products/Feature Request Board topics – Ring Community

Via two suggestions I did:

Hopefully a newer and more reliable “Computa Pranksta” mouse jiggler device will ever be released

Posted by jpluimers on 2024/05/30

For my link archive as this was a cool idea, but for many their device didn’t last that long:

[Wayback/Archive] ElectricRCAircraftGuy/eRCaGuy_ComputaPranksta_Support: Public support for my “Computa Pranksta” mouse jiggler device I sell on Amazon and elsewhere.

This device is a mouse jiggler. It keeps your computer awake. It can also be used to have some fun with your friends (please don’t take it too far–it’s meant to be used in good, friendly gest–not for any type of malicious purposes).

Notes:

Links on those USB Mouse Jigglers below, but first some links on the Computa Pranksta:

Veel Streamdeck tips in het topic “Mountain brengt DisplayPad- en MacroPad-toetsenbordjes uit voor content creators”

Posted by jpluimers on 2024/04/29

Het grappige van sommige Tweakers.net artikelen is dat er dan ineens veel tips over een concurrerend product in staat (omdat de laatste over het algemeen op bepaalde vlakke beter is).

Zo ook met diverse handige Stream Deck (van Elgato) tips in commentaar onder het artikel [Wayback/Archive] Mountain brengt DisplayPad- en MacroPad-toetsenbordjes uit voor content creators – Computer – Nieuws – Tweakers.

Learned a while ago from @Caramelia79  at Twitter: “AEG Methode.”

Posted by jpluimers on 2023/08/28

Too bad that [Wayback/Archive] Cara (@Caramelia79) / Twitter deleted their tweet before it got archived, so this lone tweet does not really make sense now:

[Archive] Jeroen Wiert Pluimers on Twitter: “@Caramelia79 @unimanatee Heute neu gelernt: AEG Methode.” / Twitter

The joke however was this:

AEG Methode:

  1. Ausschalten
  2. Einschalten
  3. Geht

It is also known as “AEG-Prinzip” and refers back to the AEG brand that was (still is?) big in Germany for household appliances and industrial products.

The not so cool thing is that by now it seams to mean:

  1. Ausschalten
  2. Einschalten
  3. Geht nicht

as about a year ago some AEG microwave appliance models show errors F606 and F254 after a firmware update: they now think they are steam ovens but cannot find the correct steam hardware:

Isotopp’s home sensor network

Posted by jpluimers on 2022/11/25

For my link archive an interesting blog post by isotopp (Kristian Köhntopp)

[Wayback] My home sensor network

I have been asked to document my home sensor network. Being married to a person with a background in web security sets boundary conditions:

  1. No cloud. We are running all services locally.
  2. No control, only metrics.

I am collecting data from a number of plugs with power meters over Wifi, using the MQTT protocol. I am also collecting data from a number of temperature sensors over Zigbee, and convert to MQTT. The MQTT data is ingested into Influx, and then read and plotted in Grafana. All of this is dockered and runs locally on an Ubuntu server.

Fixing a classic Ring Chime that does not power on any more (no blue light)

Posted by jpluimers on 2021/12/23

A well known classic Ring Chime problem is that shortly after warranty expires, it won’t power on any more (no blue light visible at all):

[Wayback] Ring Chime Pro no power – Products / Accessories – Ring Community

Usually the built-in power supply is toast, and it is relatively easy to replace this with a USB power supply.

The below video shows how to do that for a classic Ring Chime Pro.

I’ve repeated the steps for a classic Ring Chime (model 8AC3S5-0EU0) that I got from [Archive.is] Ring Chime – WLAN Türgong für Video Türklingel, weiß: Amazon.de: Alle Produkte
