ads' corner

A while ago I got a recommendation to look into a Raspbee (from dresden elektronik) as Zigbee gateway. That looked like fun, therefore I ordered one of the devices. The first step is the installation of the Pi itself and then the software for the Raspbee. 

For various reasons I decided to use a dedicated Pi for this, and don't install this on the openHAB Pi already running here:

• The Raspbee needs software from a closed repository
• During installation and configuration I don't have to reboot my openHAB system all the time
• The headless install runs a webserver, this conflicts with the redirect I have on port 80 on the openHAB system
• I still have a couple Raspberry Pi B+ here, which I don't need for other projects

The openHAB display in the kitchen is still the problem child. Occasionally it just stops, other times it does not refresh the HABpanel, even though it has a connection to the openHAB server. Then there is the problem with the network card in the Pi. And - ok, that's a server-side problem - occasionally the weather stops updating. All in all that's a lot of trouble for a display which is just supposed to run standalone.

In the latest iteration I looked into activating the integrated hardware watchdog in the Raspberry Pi. Checking the temperature it never goes above ~55°C celcius, even though the display is in an almost closed frame and can't exchange much heat with the environment. But nevertheless occasionally the Pi just halts, and stops operating.
