My full code as a backup and some useful reminders that are difficult to find online. In order not to spam z-wave communication. Only send a command when the value has changed > 4 (0-255). A join block before this combines the current (msg.payload.huidig) and setpoint (msg.payload.aansturing). Here we send the first node output only […]

Copying ESXi (free) VM’s From One Host to Another.
After taking my backup server in use I want to be able to move vm’s around and create copies. Think about a full pfSense backup for instance. After trying a few options, such as manually exporting OVF templates, copying using VEEAM Backup and migrating VMware vCenter Converter Standalone. After using all three, I have found […]
ESPEasy with DHT22 and Domoticz
I’ve found this a very cheap, reliable and easy way to have temperature and humidity measurements that are reported in Domoticz. Domoticz Setup Before we start messing with the ESP and connecting the DHT22 to the arduino, we need to create a dummy device to update the status to in Domoticz. In Domoticz go to […]
Read MH-Z19 CO2 meter to Domoticz using an arduino and esp8266
In order to further automate the ventilation of my house I want to be able to measure CO2 levels in the livingroom and have the ventilation adjusted according. This post describes how to connect everything and get the readings to Domoticz. In a next post I will describe how to use these readings to setup automatic […]
ESXi Update No Space Left on Device
So after a much to long time, I decided to arm myself against Intel’s microcode bug. I was going to update my ESXi instance, running from an USB-stick, to the latest version, ESXi-6.5.0-20180104001-standard (Build 7526125). After finding out that all ESXi updates do not have to be installed incremental I realized i only had to […]
Configure pFsense to tunnel all internet traffic from specific hosts over NordVPN connection
I will describe how I have setup my pFsense and ESXi network settings to allow all internet traffic generated by a certain (or more) VM’s to be routed trough the VPN connection whilst maintaining LAN communication between all VM’s. Preparing network structure in ESXi This can be skipped for now, i’ll update this section when […]
Solar panel power monitoring in Domoticz using a kWh pulse meter.
Because my solar inverter has no easy way of me accessing the current or total generated energy I chose an approach that will work with 100% of the inverters available. First of all I use an MID kWh meter, specifically this one. Other, similar models will also work but make sure it has a pulse […]
SATA Passtrough ESXi 6.2 with Supermicro X11SSH-LN4F
This page describes how to enable hardware passtrough in ESXi (6.5 at the moment of writing this) for storage devices that do not show up are greyed out in the ESXi’s PCI devices list. I have written this specifically for my motherboard but I assume it can be adopted for many different systems. Enable […]
Shutdown Ubuntu when APC UPS battery runs low.

This how-to explains how to automatically shutdown an Ubuntu (16.04lts) instance when an APC Smart-UPS equipped with an AP9617 Network Card. The network card is convenient since i have multiple VM’s running in an ESXi environment these can all be shutdown individually. Installation When using systemd This example assumes you are using a APC Smart-UPS […]
