PyEto works great, but need a lot of data to compute.

Please have a look at https://github.com/sherzodr/penmon which in a simple python class can compute Eto with minimal data.
The precision increase if you have more data like wind, dew and solar radiation.

There is also this project:
https://github.com/hwestbrook/evapotranspiration_calculator
It makes for a very clean ET calculation based on this paper:
http://n4te.com/x/7163-ae45900.pdf
I ported it to Java with a little clean up:
https://gist.github.com/NathanSweet/ee6f669c70fbd2ee82907c81138baa67
The values it needs are:

dayOfYear // 1-366
tempMinC
tempMaxC
relativeHumidityMin
relativeHumidityMax
windSpeedAvgMs // At 2 meters above the ground.
solarRadiationAvgWM2
albedo // 0.23 for grass.
elevationM
latitudeDegrees

thanks! Version 2.0 (currently in beta) provides a way to add calculation modules. Feel free to take a stab at adding these as calculation modules.
