A new year a renewed #introduction

I am Dude, associated with the movie but there the comparison ends.

An updated #Introduction for 2025:

I’m a dad, #cat whisperer, #computer nerd, occasional #gamer, and #movie lover. I’m a #quality minded #professional and I make my own #homebrew beer. #freebsd. Enthousiast I love #fitness #walking #programming in #python and #3Dprinting. Busy with #homeassistant and more.
Ik spreek voornamelijk Nederlands, Engels een beetje Duits.

Hm, thanks #GitHub - I had bookmarked this promising #homeassistant integration a while ago but completely forgot about it. Now they released a new version, it showed on my dashboard, and this worked as a reminder.

Given that we have a heat pump, we don't use thermostatic radiator valves but this integration might be handy for people who do.

This #homeassistant card I am using for quite a while now - looks really nice and is highly configurable:

github.com/flixlix/power-flow-

#homeassistant

"The Goal of this card is to provide an easy to understand and visualize way of displaying the current Power Distribution coming from and to different sources, such as solar, grid, home batteries etc. Furthermore, this card aims to expose a lot of customizability and control of its behavior to the configuration [...]."

To find interesting (new) #homeassistant integrations, sample configurations etc. it's worthwhile to search for "lovelace" or "homeassistant" on #GitHub from time to time.

I just did that and stumbled over the following integration:
github.com/nielsfaber/alarmo

"[Alarmo] allows to combine existing sensors for creating a security system for your house. The integration is comparable with the Manual Alarm in HA, but also has some additional features that makes it easier to use."

I posted about the Open Mower #robot already, and it is pretty neat. https://openmower.de/

But after fighting with a Roborock vacuum, trying to get it to pair with a used auto-empty dock that I bought on eBay, and failing, I really wish we had open source, upgradeable robot vacuums right now. Maybe taking a popular series of chassis from Roborock, Roomba, or Shark or Dreame, and giving it its own onboard processing plus a “brain” in something like a #HomeAssistant extension so that it didn’t rely on GPUs somewhere for image detection and didn’t send metrics off to a server somewhere.

Folks could design and build their own add-ons as they need them or can afford them. For example, there’s an upgrade available commercially to add a mop dryer to this dock, and it’d be neat to add that if I can get the dock working, because it’s less likely to get moldy. But also other companies have released a kit that replaces the clean and dirty water tanks on the dock with plumbing hookups — I can’t use that anywhere in my house because we don’t have laundry room or a large bathroom that it could work in, but others might want to design and build their own as an upgrade for this hypothetical open source robot vacuum.

And as a reminder, I’m pretty sure that Roomba got bought by Amazon and is now just another little Internet-of-Surveillance tool for them.

A hypothetical open source vacuum that doesn’t just bump around randomly until it is out of charge would be:

The base unit with onboard lidar and a camera for image detection. Quiet vacuum with some power. A mount for a future mop to be installed (or ability to replace the rear bottom shell to support one, later.) A basic dock that charges and provides some beacon to SLAM during operation.

A mopping upgrade.

An auto-empty dock for the dust canister.

An even fancier mopping and auto-dustbin-emptying dock. Upgrades possible: heated mop dryer and plumbing kit.

Make it all run on ROS and packable/configurable. Let it tie in to HomeAssistant automations and scenes.

It all sounds very cool but I haven’t done a ton with robotics in a long time.

30/x #diywärmepumpe

Ich hatte jetzt auch endlich mal Zeit, mir in #homeassistant einen Template-Sensor für den Seasonal Power Factor (SPF, dt Jahresarbeitszahl) zu bauen. Dauert eigentlich eh nicht lange, aber wie es halt so ist...

Momentan haben wir (noch) einen SPF von 5.69, was ein extrem guter Wert für eine Luft-Wasser WP ist. Mal sehen, wie weit der über die Heizperiode noch runtergehen wird.

24/x #diywärmepumpe

✅ Separaten Zähler für die WP mittels "RS485-to-ModbusTCP Bridge" in #homeassistant eingebunden

Der Zähler war noch von der PV Installation übrig und bereits so installiert, dass er den Gesamtverbrauch der Wärmepumpe (also inkl. Regelzentrale, Heizstab, Umwälz- und Zirkulationspumpe) misst. Nur so macht eine Energiemessung für mich Sinn.

Der Zähler liefert umfangreiche Daten über RS485, die ich jetzt mittels einer Protoss PE11-H Bridge über ModbusTCP auslesen kann. 👍😎

22/x #diywärmepumpe

✅ Modbus TCP Anbindung für die PV-Überschuss Steuerung funktioniert

Technisch eine m.E. saubere Lösung: Ich schreibe einfach mittels einer #homeassistant Automatisierung alle 5 Sekunden den aktuellen Leistungswert des Hauptzählers (Einspeisung oder Bezug) in ein spezielles Register. Den Rest macht die Wärmepumpe.

Konfigurierbar ist sowohl eine prozentuale Leistungserhöhung bei PV-Überschuss, als auch eine Erhöhung der Warmwasser- und Vorlauftemperatur. Nice!

21/x #diywärmepumpe

✅ Panzerschläuche außen gedämmt

Ich gehe hier "all-in" - gedämmt mit Kautschuk entsprechend GEG 200%

✅ ModbusTCP Anbindung an #homeassistant hergestellt

Aktuell lese ich damit nur die wichtigsten Kenngrößen aus und zeige diese in HomeAssistant an. Wie ich die WP dazu bewege, bei PV-Überschuss die Temperatur des Brauchwassers zu erhöhen, muss ich noch herausfinden. Es scheint da verschiedene Möglichkeiten zu geben...

Continued thread

Mit am meisten freue ich mich ja auf die Integration in #homeassistant

Natürlich abgesehen davon, wenn dann hoffentlich auch im Betrieb alles dicht ist... 💧👀

Die Wärmepumpe kann Modbus TCP und der Hersteller liefert eine ausführliche Beschreibung aller Register etc. Und man kann so ziemlich alles auslesen und steuern wie es scheint. Es gibt auch schon Beispielkonfigurationen.

Das wird ein Spaß! 😀👍
