VegeHub - Trouble Shooting Guide

Top 6 Reasons Your Hub isn't Working

  1. You're using the wrong network password. Make sure you are using the right password, and that the letter case is correct, and that you are logging into the correct network.
  2. Your batteries are dead. Make sure you are using new batteries, and that the voltage to the hub is at least 6V.
  3. The battery cable leads have come loose out of the terminal blocks. Tug on the cable to make sure it is secure. Make sure no wires are shorted or touching.
  4. The battery cable leads have the wrong polarity. The red wire should go to the V+ terminal, and the black to GND.
  5. You've pressed wrong setup button. Each button has a corresponding LED. When you are using your phone to select and setup the hub's WiFi credentials, make sure the red LED is lit. When you are trying to access the configuration pages on the hub make sure that the Yellow LED is lit.
  6. Your router's firewall is blocking the Hub. Log into your router, and make sure that the firewall isn't blocking hub trafic.
  7. Your USB drive is formatted with the wrong format. The drive must be formatted with FAT16 of FAT32. It will not work with Microsoft's latest abomination "FATeX"

General Advice

When figuring out what could be wrong, you need to divide the problem to conquer it. Remove all sensors from the hub, so that you can rule out that the problem is with the sensors.

After the VegeHub has been configured to talk to a desired server, it will periodically contact the server, and send its data, according to it's sample rate. Whenever it sends an update, it will blink the green LED. If it is unable to connect to the server, or if there is some other problem, it will blink the red LED instead.

VegeHub Send Data LED

You should be able to see data on the server websites, as updates are sent.

When you are initially getting familiar with the VegeHub, set the sample and update periods to 1 minute intervals, for a high update rate, so that you can more quickly see if you are receiving data. Then, after you have everything working, set the sample and update periods to larger values to conserve battery power.

Make sure you trim any wires going to the terminal blocks, so that they are fully covered with insulation, as shown in the diagram below. If you don't trim the wires, they could short together if the wire is twisted at all.

Bad and Good Wiring Examples

Make sure your router is not blocking the VegeHub with any firewalls.

Symptoms with Solutions

  • Can not connect a laptop or phone to the Hub as a WIFI hotspot. Make sure that the red LED is lit. It should be the only LED lit. If all 3 LEDs are lit then most likely you have a bad battery. Use a voltmeter to test the battery voltage and make sure that the voltage is above 6V.
  • Can not bring up the setup pages on the hub. Make sure that the yellow LED is lit, and is the only LED that is lit. Make sure you have the right IP address for the hub. Make sure that you have any firewalls turned off that might be blocking it.
  • I've set up my own private web server on a Raspberry PI, but the hub is not posting data to it. Many computers have built in firewalls. Make sure you have allowed access to your web server, and it's port.
  • I insert the USB drive, and can see the drive leds flash, but no files are written. The drive must be formatted with FAT16 of FAT32. Reformat your USB drive, or use a different drive with the correct format. Some newer and larger drives use FATeX, which will not work.

VegeHub WiFi Sensor Hub -Diagnostic Lights

  • Upon Power Up All 3 LEDs are lit. Most likely the battery has too low a voltage and needs to be replaced.
  • Red LED is blinking Failure to connect to the WIFI network.
  • Green LED is blinking Failure to connect to the server. Could be that you have bad SSL certificates, and need to update them.
  • Yellow LED is blinking Failure to get the Internet time. It could be that the NIST timeservers are down.

Rare Issues

If you have more than one router on the network, make sure that they two router's DHCP have not fallen out of sync.

Diagnostic LEDs

There are three LEDs on the VegeHub/VegeSprinkler, These will turn on or blink in combinations, depending upon the state, or error code of the hub. To view their meaning see the Diagnostic LED Guide.
