I have just added a SunAirPlus to my OurWeatherStation and when I connect the Grove Connector from the SunAirPlus board my OurWeather will not boot. Leaving the connector unplugged it boots fine but no information about the power which makes sense.
In testing I have removed all but the OLED display and the SunAirPlus attached to the OutWeather board. The OurWeather board has been updated to version 031 of the software. I have checked and double checked to make sure I have the three connections to the SunAirPlus board correctly attached (leaving out the red wire).
Can you help me figure out why it will not boot? I don't get any messages on the OLED display. If I connect power to a separate 5V power adapter but leave the SunAirPlus grove connector attached same problem. Remove it and all boots well.
One final bit of information, when it won't boot, I am seeing the SCL and SCA lights near the grove connector on the OurWeather board flicker dimly. I don't know if this helps you or not.
Thanks

Put on the RED wire to SunAirPlus. It needs 3.3V. Tell me if that makes any difference.

I connected to VCC and still no go. I have a second weather board and same result. I've ordered another sun air plus, any other ideas?

One more question. When you plug the SunAIrPlus board does the white light on the OurWeather Board stay on?

I got another board today and it worked like a champ! Chalk this one up to a bad SunAirPlus.

Excellent. The two most likely failure modes for SunAirPlus is static charge and wiring the VCC to GND and vice versa!
