FooGadgets

I got a tip from a NetHome user about a really interesting site called FooGadgets which sells wireless sensors using standard wireless thermometer protocols. You can for example connect 16 1-wire thermometer sensors to one sensor-card and they will show up as 16 separate thermometers in NetHome.

They also build a wireless pulse counter which can be attached to "blinking" energy meters so you can get data about your energy consumption. I am currently working on a HomeItem for the Wireless Pulse Counter, which will be able to presents graphs and values over the energy consumption in a house.

Fine Offset Rain Gauge

Support for the FineOffset rain gauge is now also included in OpenNetHome. The new FineOffsetRainGauge-Item keeps track of rain fallen the last hour, the last 24 hours, the last week, the last month and the total amount of rain. The graph shows the amount of rain fallen between each log point, which is every 15 minutes. The resolution of the sensor is 0,3 mm.
Unfortunately, the Tellstick does not currently support this sensor, so it will only work if you use the audio interface with OpenNetHome.
It is available in the nightly build.

Fine Offset


Support for the FineOffset protocol for temperature and humidity sensors is now added to OpenNetHome. As usual, the brand names of the products vary between countries, and in Sweden for example they are sold under the name “Viking”. The usage in NetHomeServer is similar to the Oregon Scientific, so there are two new HomeItems: FineOffsetThermometer and FineOffsetHygrometer. As with the Oregon sensor, auto discovery is supported in OpenNetHome, so if there are sensors in range, they will automatically be presented on the Create/Edit-page. Note that not all FineOffset-sensors actually have a humidity sensor included. Graphing of values is of course supported as for the other sensors. Implementation is available in the nightly build. 

I am also working on support for the FineOffset Rain Gauge, but that is not finished yet.

Oregon Scientific

I have now added support for the Oregon Scientific-range of sensors to OpenNetHome. As with the UPM-sensors there are two Home Items available to use them: OregonThermometer and OregonHygrometer. If the sensor model has a humidity sensor, you can connect both items to it. As usual they both support graphing of the values.
As usual I cannot test all variants. I have tested with the THGN132N which is a thermometer/humidity sensor. I have however added code for the THGR122NX, THGN123N, THGR810 and THGR810 temp/hum sensors, the THN132N, THR238NF and THWR800 temp only sensors, the WGR800 wind sensor, the RGR968 rain sensor and the BTHR968 temp/hum/pressure sensor. The support for those is a bit more theoretical, I have implemented it according to specifications, but have not tested them. Oregon Scientific also have three versions of the protocol: 1.0, 2.1 and 3.0. I have now implemented the 2.1 version. 3.0 would be possible to add, but again I don't have any sensors so, that would be a bit too theoretical implementation and I don't know how commonly used it is. Implementation is available in the nightly build.

OpenNetHome in the media


I have now seen two articles about OpenNetHome online! One in the german Linux-Magazin and one in the greek site osarena.net. It is fun to see that the interest for home automation seems to be growing.

Telldus


Since NetHome now officially support the Telldus Tellstick, the project now also has its own page on Telldus site for 3:rd party applications - check it out on here. Currently I am slowly moving documentation to the new site - a bit boring, but I guess it has to be done...

NetHomeServer 2.0


I have now finally released NetHomeServer 2.0! Release notes are available here. The final struggle was to get the drivers for Tellstick to work on Windows 8, but with great help from Telldus support we got that working. They signed the VCP-drivers needed for NetHomeServer - thanks!

For those who have been using the nightly builds, there are no other new things in there, instead there are two other things that have changed: The first is that NetHomeServer is now also open source, distributed under GPL V3. It is available on GitHub. Previously I have opened my private repository for those who have wanted to contribute, but now I can just say: Clone us on GitHub!

The second thing is that NetHomeServer now has a new site. Since it is an open source project, I thought a .org-address would be more appropriate, so www.opennethome.org is the new home - please visit and have a look. The old wiki will still be there for a while, I have not moved everything over yet.
