Here is a screenshot, notice the extra ‘Sensors’ link on the top right to access [...]

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 [...]
