Good morning dancingBear,
What you want to do can all be done with Blynk, http://www.blynk.cc/ , You can bride several WiFi devices to a single device and monitor them from anywhere over your cell or pad,,, you can even set up your own server. The data can also be sent via text, e-mail, ITTT, and data sites... Just about any Android, RPi, ESP8266... WiFi/BT device will work. They also have a large community base on which to draw form...
