You should checkout the Aosong AM2320. It's a pin compatible upgrade for the DHT22 (AM2302).
The AM2320 sensor includes I2C protocol, as well as legacy 1 wire.
Comes in a black plastic case, around the same dimensions of a DHT11.
I even have an I2C driver to share: https://github.com/mcauser/micropython-am2320
Works on my ESP8266 port. I2C methods on the Wipy should match or be easy enough to translate.

Thanks for a tip! I didn't know about the AM2320 model. I switched to Bosch BME280 in the meantime, but AM2320 looks nice too and costs less.
