It looks like iI cannot combine the Grove Sunlightsunlight sensor and the Grove DHT22 Temperaturetemperature and Humidityhumidity sensor. I can't figure out why.
I'veI have the following setup: Seeeduino CLOUD (Arduino YUN clone) Grove Shield Grove Sunlight sensor connected to a I2C port Grove DHT22 Temperature and Humidity sensor connected to port A0
I'm sending the data to Initialstate.com
- Seeeduino Cloud (Arduino Yún clone)
- Grove Shield Grove sunlight sensor connected to an I2C port
- Grove DHT22 temperature and humidity sensor connected to port A0
I'm sending the data to Initialstate.com. This is my code:

This is my code:
When I run this code, the Serial monitor will correctly display the data string I want to send with all values. However the data is NOT sendsent. Only when I comment out one of these lines in the Looploop() declaration the data is sendsent to Initial stateInitialstate successfully. Obviously without the data commented out:
