KIT80949P - Wireless Sensor Node - Solar Kit

Thank you for all your answers.
I understand all you say, but for a “cheap” wireless node with wifi be on each, i cant do your solution.
1 analog and 1 i2c is enough i think for each.

But…
For example i wich an pressure sensor like HP3, BMP085, HP03S who are in i2c, i can have :
a temp/hum in analog port and a pressure in i2c port.
Right ?

Other :
I think it can be possible to made a simple mux for i2c port ?
1 sort for 2 or 3 analog input
1 sort for 2 or 3 i2c input

that make the node with max 6(4 ?) sensors, afforable and amortize the cost of the wifi bee.
For example for soil moisture and soil temp in 2, 3, 4 depth . in one node

Last but not least, i still have ph sensor and salinity/Chlorine sensor on boxes for the swimming pool, can i take the signal there ?

Another :
I think i can retrieve sun hour/solar radiation only with the voltage of the solar panel, but how to send the value with the wifi bee… I’m searchikng everywhere on the wiki before.

Thank for all
