Alecto WS-1300 Wireless Plant Sensor teardown

The Alecto WS-1300 is a wireless plant observation system. It consists of a base unit and one or multiple plant sensors. The default system includes the base unit and one plant sensor. Optional sensors can be ordered from the manufacturer (Alecto). Although it seems Alecto just re branded a Chinese product (more about that later) […]

Smartmeter update: permanent cable

Today I received a FTDI DS_TTL-232R cable ($12 on ebay), this cable allowed me to create a more permanent solution for my smartmeter. Here is the old cable/test setup: And here is the new cable (I replaced the six pin female header with a RJ11 crimp connector):

New smart meter installed (Iskra ME382 and Landis + Gyr gasmeter E06140)

Last week Liander, one of the biggest energy network maintainers in the Netherlands installed a new smart meter at my place. Actually they installed two new meters: the Landis+Gyr E06140 to measure gas usage and the Iskra ME382 to measure electricity. Both devices are linked together and the electricity meter provides a P1 port, this […]

GreenWave Reality PowerNode (bar) first impression

Recently my colleague Frank (props to him) discovered this device which could well be a good alternative to the (ever delayed) Qees power strip. We both decided to order one of these devices. It’s a very reasonably priced device (€50,-) for it’s specifications: 6 switchable and measurable sockets Overcurrent (10A fuse) -and surge protection 0.1W […]

Horstmann HRT4-ZW Thermostat – open ends

A few weeks ago I received an e-mail from a guy who rather stays anonymous, but had some really great additional/detailed information about the HRT4-ZW thermostat. There’s some things I missed out, or did configure along the way while tinkering with this device but forgot to mention. So here’s a post about these “open ends”. […]

The power of open source and social coding

A few weeks ago I published the open-zwave Python wrapper. I basically started with a small wrapper suiting my personal needs. After a couple of days I was asked to share the code on Github. Until then I never used Github before. I did not expect anything from that whole social coding thing. But then […]

Horstmann HRT4-ZW Thermostat

About one month ago I ordered a Horstmann HRT4-ZW thermostat. I came across this z-wave thermostat while I was surfing across the web. As far as I know this is the only EU thermostat available right now. Some of the features I like and I was looking for in a z-wave thermostat: Control the setpoint […]

From Python module to GUI, software evolution

Having a Python module to control a z-wave network is great, but not really directly useful in practice. I can’t imagine myself switching lamps on and off everyday using a Python script. However, with a nice GUI it will become much more useful. Today I created a GUI around the py-openzwave module, for use within […]

py-openzwave, a python wrapper for open-zwave released!

Today I am releasing py-openzwave, which is a python wrapper around the open-zwave project. The wrapper allows you to control a z-wave network from python. This wrapper is still a work in progress, but the basic skeleton is in place (network scanning, and turning a device on or off). At the same time I am […]

Compiling open-zwave with MinGW

Open-zwave is a great project, it provides a software interface to z-wave networks. Z-wave is a popular home automation protocol. With more and more devices coming I was interested in adding z-wave support to my own home automation software. Being a python fanatic, I wanted to use open-zwave from within python. The first step in […]
