hi,

i need a prebuy advice for the following:

a meeting room with 5 radiators, which 

- has no cable internet connection

- is used regularly on 2 days a week ( i will make a weekly plan !!)

- sometimes it need to put on the heating from at home for unregular time intervalls for other peoples that will use the room  ( manually put on, off from at home)

- no one lives in the meeting house, but every day i want to control the temperature from at home

- the meeting house is 12 miles apart from my home.

As a low budget solution we have a wlan router there with a integrated sim card and 1 GByte budget per month, after the budget is consumed the hight speed connection is slowed down to a flat rate connection with only 64 kbit/sec.

1. How many Mbyte/Gbyte transfer volume per month will the hub need to connect with the internet for daily sync ?

    I mean only the connection between the hub and the internet. Not the traffic between the hub and the several local KE100 devices.

    Suppose i connect every day two times to get a status of the temperature of the devices.

2. How do i connect from at home from laptop or smartphone with the hub in the meeting house ?

many thanks in advance
