What's your Favourite IOT platform that you use and would recommend to others, I like Thingspeak as it's pretty easy to use and setup, but I've also been having a look at Google's IOT and although the learning curve looks really steep I think it could be good.
My favorite is Thingsboard (https://thingsboard.io/).
It is very flexible and on of the few that not only present data, but also has actuators (e.g. buttons, knobs) to send data to the devices.
I use thingspeak and EASYIOT.
Depends on what you want to do specifically as EASYIOT has a few features that thingspeak doesnt and vice versa.
Like that both are quite simple to use.
