WeIO : a new IoT plaform

Back in june, I went to the Maker Faire which took place in Paris.

I saw for the first time a new little but powerfull platform which was under development : the WeIO. It looked like quite promising.

Creators of this new “Web of Things platform” just launch a crowdfunding campain on INDIEGOGO. Their goal was to reach $10.000… After 2 days, they reached… $9.568 ! No more early bird offer but you can still support them and pre-order this new gizmo ! I just did !

Can’t wait to play with it…

NetAtmo : now they have a connected thermostat !

netatmo3NetAtmo is a french company now well known for its connected weather station.But not only ! They now have also a connected thermostat so you can control your home heating from internet, using their own app or the provided API.

Much like Nest thermostat (but far less expensive…), it can “learn” from you behavior and just stop and start heaters when needed.

Nice… I think I will replace my “old”, not connected & closed Delta Dore thermostat !

Discovering openHAB

I was looking for a software I could use to build a neat remote control for home automation on iPhone and Android tablet.


I first found OpenRemote which is quite nice. I already used it to build a remote for my IP remote controlled power strip.

But OpenRemote it did not work really as I expected (may be a bit complex to use) and the OpenSource version seems not to be really active on the development side.


So I did look around to find an atlernative and finally discovered openHAB quite a while ago. When I first discovered this project, current version was 1.2.

Since then, the latest release is 1.4 and they have a very nice new website.And, most importantly, they build my.openhab.org which allows managing your hosted HAB instance from the Web (currently in beta).

With openHAB, you can build simple interface for the Web, iPhone, iPad, or Android devices. It is probably not as powerfull as OpenRemote but then is quite a few “bindings” for many devices or protocols (http, tcp, ntp, Google calendar, EnOcean, KNX…) More than 50 are available today.

With a few lines of code, you can build a nice interface to your home automation systems…

… on iPhone


… or Android !



Nice !

Raspberry Pi has a new friend : ZiBASE Mini

Zodianet is a french startup which sells a home automation box : ZiBASE. They just released software running on ZiBASE for the Raspberry Pi : ZiBASE Mini. It is available as an SD card image or as a debian package.

There is a (not so) basic free version which is working with ZWave or enocean usb dongles. You will have a pay a licence for advance home automation (video streaming, data historization, scenarios…)

It is a nice way to start as software is free and Pi is cheap ! And it is known to work on CubieBoard also !

I’ll try it ! Downloading…

RFM12B signal strength meter using emonGLCD

I just discovered that Martin Roberts designed a very nice RF scanner and signal strength meter (SSM) using an emonGLCD. With one very simple hardware modification (you will loose the ability to use the LDR though), you can get the emonGLCD to work as a RF scanner ! All instructions are here. I followed them and within minutes, I got my RF scanner working !

GLCD SSM 640x480

The softwaremake the scanner easy to use and configure using the three emonGLCD push-buttons. You can configure the following parameters

  • Trigger level : minimum signal level required to trigger the display
  • Trigger position : position on the display of the signal that caused the trigger
  • Base level : minimum signal level which can be displayed (-80 or -100dBm)
  • Glitch detector : with this on short signal pulses which could be missed by a normal scan will show up
  • Timebase : period of a complete scan across the screen (16ms-16s)

Here are screenshots at  respectively 16ms, 32ms, 128ms and 16s :

Very nice !
