These are some basic problems. For anything not covered here, go to the HeaterMeter online community on The Virtual Weber Bulletin Board tvwbb.com. For most troubleshooting, using the rPi USB power input is preferred in order to avoid the chance of subjecting the rPi to 12V which will definitely fry components on it.

I built the whole thing, but nothing happened when I plugged it in.

  • Start by ensuring you can connect to openwrt on your Raspberry Pi see [HeaterMeter 4.x Software](HeaterMeter 4.x Software#configuration)
  • If you can connect to the Raspberry Pi, look at the system log (Configuration -> Status -> System Log) to see if your heatermeter was recognized.

  • Verify that all necessary components are on the board and in the right place.
  • Ensure sure you pushed solder through on every connection so that a connection is made on both sides of the board.

My Wifi interface never gets an IP address

You can't have both the wired and wireless adapters on the same subnet. Even worse, DHCP sets the wired ethernet as the gateway for the wireless which means the wireless can't talk unless the wired is plugged in.

Some people have had success by ensuring the wired interface does not start at boot (go to the advanced tab of the LAN and uncheck the auto start option and reboot the device) * This is risky if you configure the wifi configuration wrong and don't have a usb keyboard and hdmi output in order to recover.

I get an encoding error on the Configuration page

Set the names of all three probes to override weird characters. Mine are creatively named "Probe 1", "Probe 2", and "Probe 3".
