I updated my GitHub repo: http://github.com/nemik/arduinoponics with code I wrote for the OpenWRT firmware (version 8.09.1). It provides an AJAXy-updating page to OpenWRT’s Luci web-interface which displays the analog pin values from the Arduino which the Arduinoponics sketch runs on.
Here is a screenshot, notice the extra ‘Sensors’ link on the top right to access the [...]

I did just that when writing some code for the hydroponics monitoring setup on my Fon2100 router running OpenWRT. After trying to opkg install ntpclient and getting a segfault and NTP not working, I restarted the network on it [...]
