New, good batteries (tried 2 different batteries). Plugged the USB power control into the system (wasn't using it, just had SunAir hooked up) and now the system keeps shutting down due to low voltage. Why?
:
SunAirPlus Currents / Voltage ----------------- LIPO_Battery Bus Voltage: 0.00 V LIPO_Battery Shunt Voltage: -22.04 mV LIPO_Battery Lo
ad Voltage: -0.02 V LIPO_Battery Current 1: -220.40 mA Battery Power 1: 0.00 W
Solar Cell Bus Voltage 2: 1.05 V Solar Cell Shunt Voltage 2: 0.00 mV Solar Cell Load Voltage 2: 1.05 V Solar Cell Current 2: -0.00 mA Solar Cell Power 2: -0.00 W
Output Bus Voltage 3: 4.94 V Output Shunt Voltage 3: 30.24 mV Output Load Voltage 3: 4.94 V Output Current 3: 302.40 mA Output Power 3: 1.50 W

buckwester,
I replied to you last week ago, but the reply is not here. I must have hit the wrong button.
You have another i2C device (probably a temperature/humidity sensor like the HDC1080) on 0x40 and so you aren't reading the SunAirPlus board correctly. I have had the exact same problem.

Hello,
I have the same issue...systems works fine, 0 battery voltage, and the system shuts down after 5 minutes (the normal software behavior when the battery voltage is low).
I do have the internal humidity/temperature plugged into the I2C MUX (or on the I2C bus on the grove board).
How can I fix this/wire this/address change this so the SunAirPlus and the Temp/Humidity sensor can work together? I also still have the OLED plugged in as well.
I'm a little shaky on the I2C MUX vs the Grove I2C vs the I2C 4 extender.
Thanks!
MDH

MDH,
The I2C Mux breaks the address space of the I2C bus into four segments. The Hub just allows you to put more devices on the same segment.
Please post what you are reading from the SunAiPlus board and make sure you have the jumpers installed on the I2C Mux board. Post a picture.
