CPU Charts

I finished a new page today, containing CPU Charts for all of my virtual machines. This way i can keep track of what’s going on ‘√≠nside’ my virtual machines, without having to log on to the server all the time. The data for these CPU Charts are produced by a Powershell script running on the host, that periodically does some WMI querys and stores the results in a SQL Server table.

I’m planning on expanding the monitoring of the virtual machines by adding things like disk usage, uptime etc so i have a good view of how the systems are performing and whether they need attention or are just running fine.

Time for a new central heating

Yesterday we got a letter from the company that does the maintenance of our central heating. It said our current central heating was to vulnerable to failures and we were offered an upgrade to a newer central heating at a reduced price. Well, it is true that our central heating has caused us a lot of trouble through the 10 years that we live here. So i understand the reason why they want us to upgrade to a newer model from a different brand. But i’ve got my own wishes…
Our new central heating should be controlled by means of the Opentherm protocol for instance, so that i can ‘tap’ the communication between central heating and the thermostat and incorporate the data that i can get out of that, into my Domotica System. And i’ve made my choice: our new central heating will be a Remeha Avanta, controlled by a Remeha Celsia 20, including a so-called gateway for attaching a RS-232 cable to it and tap the communication.

Ethernet-enabling my hardware

In order to be able to virtualize my 3 24/7 PCs to one single machine (by using Windows Server 2008 with the upcoming Hyper-V), i need to get some devices Ethernet-enabled, like my ACT TI213, the LED-bar, PTZ-control for my Sone EVI-D30 cameras, RFXCOM receivers and transmitters, etc. etc.
I ordered a Ethernet-RS232 converter earlier this week to connect RS232 devices to my LAN and ‘talk’ to these RS232 devices by using TCP. It’s very simple; you set the IP address and Port for the Ethernet side, Baudrate etc. for the Serial side, and off you go. Together with some POE (Power over Ethernet) plugs this will reduce the cabling in our house, cause Ethernet is always nearby..

LEDBar accessible from Internet

A LEDbar is one of those gadgets that everyone should have. Connected to my HA system i can display anything i want on it; RSS feeds, traffic information, whatever i want. So i bought one, started programming and in a few hour it was operational. Just for fun i placed it on front of my webcam, and changed that page so you can enter a text, choose a color and speed, and display it on the LED-bar. Ain’t that funny?
