Smart Home: “Your Laundry is done!” with Homematic and Symcon

I mostly do my laundry twice. The reason is not a obsessive-compulsive disorder or because I love¬†doing laundry…I just forget to get it out and want to have fresh clothes when I peg out washing .)

Therefore I seeked for a solution to be remembered, of course in an automated way with notifications about the start and stop of the washing machine (Push Message, Audio Play)¬†as well as …

Extending Homematic CCU2 Range

I had one problem with the Homematic CCU2: The radio range.

Some actors or sensors kept having connection issues and some others simply were out of the radio range. The goal was to get a power adapter connected 2 levels under our apartment and get rid of all those warning messages.

Cosnidering the small antenna of the Homematic CCU2 in the below pictures (yes, this tiny black thing is the …

Alexa, how much water did I drink today?

I have received my Echo device some weeks ago and started to use the Symcon skill which allows easy yet cool use cases such as turning on the Homematic or Hue lights.

The more advanced scenarios can be implemented with the great Symcon module for Alexa provided by Patami. Thank you for the great job you did!

My first scenario is directly related to my last post here: Measure water

All you guys with fitness trackers, smart watches¬†or who are just interested in IoT may know the function to track daily personal¬†water consumption through mobile apps or widgets on the wearable devices.

Automated Backup with Robocopy, PowerShell and Symcon

Some time ago I started to learn PowerShell a little more and when it comes to dealing with copy processes, I stumbled upon Robocopy, again. This time I decided to get familiar with it and use Robocopy together with PowerShell to automate my backups.

I got rid of my high power consuming server as a 24/7 machine and built a power saving server while using the old one¬†for virtualization …

For one of my recent projects I would need to update IP Symcon variables from a PowerShell script.

I found the following approach handy and adopted it:

JSON-RPC Web Request from within PowerShell

It’s been a while since I worked on this script¬†but as far as I remember, I struggled with the “payloadJsonRPCVersion”. I had to provide the version in the JSON payload.

JSON_RPC.ps1 contains¬†the two functions you …

Wall mounted iPad for Home Automation (Symcon)

I decided to use my old iPad2 as a smart home console. Have been looking around for a ‘clean’ and simple wallmount which I could install in the entrance area of our flat. Finally I found this one here at Amazon:

Migrating IPS, AD, DNS, Kodi to low energy server


long time no see ūüôā

Meanwhile we moved to a new flat and added a lot of home automation and IoT stuff (hope to have enough time to post about it).

While connecting everything in the new flat and considering the power consumption charts in Symcon I found the 100W my current central server consumes too much for the few 24/7 functions it really does. It is an ESXi …

…und dann ist man pl√∂tzlich Student, der Internetanschluss wird erst in mehreren ¬†Wochen aufgeschaltet und Kabelfernseher ist auch nicht vorhanden. Die Optimale M√∂glichkeit unter Leute zu kommen? Back to the Roots? Bestimmt, aber trotzdem kein Grund die medialen Erneuerungen des letzten Jahrhunderts links liegen zu lassen ūüėČ

Kurz zur Situation:

Der Internetanschluss wird erst in einigen Wochen aufgeschaltet

RPi Humidity and Temperatur Sensor DHT22 in IP Symcon

Today I would like to quickly present one of my current projects, i.e. adding the Raspberry Pi wired with different kind of sensors to IP Symcon. With the sensor data in IP Symcon we can log changes and generate reports upon those, for instance. So we are getting data from the Raspberry Pi, or -to be more precise we push data from the Pi to IP Symcon by invoking JSON …

IP Cam in IP Symcon einbinden und steuern

Vor einiger Zeit habe ich mir die DodoCool IP Cam aus China bestellt, die ca 20‚ā¨ gekostet hat. Ehrlich gesagt wusste ich vorher nicht genau, dass es eine “DodoCool” wird. Es sah einfach wie ein Foscam Clone aus und die sind erfahrungsgem√§√ü ganz ok. Die reine Einbindung in IP Symcon geht √ľber das Hinzuf√ľgen eines Objekts – in diesem Fall ein Media Objekt. Als Medientyp w√§hlt man “Stream”. Die IP …

Nachdem ich den Gro√üteil der Wohnung mit HomeMatic Unterputz Schaltaktoren ausgestattet habe (HM-LC-Sw1PBU-F, HM-LC-SW1-FM, HM-PBI-4-FM) kann man nun die Lampen im Wohnzimmer, Flur, Esszimmer, Bad und HomeOffice √ľber IP Symcon steuern.

Ohne viel Erfahrung im elektrotechnischen Bereich, habe ich mich an den Elektriker meines Vertrauens gewandt, um mir ein paar Anleitungen und Basics zu besorgen mit denen ich die folgenden Komponenten installieren konnte:

Heute fasse ich mich kurz. Ich habe 2 Homematic Zwischenstecker mit Energie- bzw. Strommesssensoren. Einen in meinem HomeOffice, der andere wird in der “Zentrale” im Wohnzimmer benutzt, an dem Server, HTPC, TV, Beamer, AVR… h√§ngen.

F√ľr die Energy Counter habe ich als Aggregation “Z√§hler” und nicht Standard verwendet. Beim Power-Sensor ist Standard geblieben, weil ich die max. genutzte Watt, und nicht eine Summe daraus darstellen m√∂chte:




Der HomeOffice-Z√§hler …
