I'm starting this thread in the hope that it will be an ongoing discussion about the WM100 Wifi Hub.
There are many threads containing WM100 questions and problems and a couple of old threads about the design and future, but, as far as I could find, none that contained general information that would help newcomers to the WM100
As those who have WM100's know, this is a very unusual device, not only in the X10 arena, but it is also unlike any other IOT (Internet Of Things) or even any other (wifi) connected device. It is poorly documented, has a number of hidden "confusers" and the highest praise that I can give it is that it "has a lot of potential"
So, I'll start with one of my own discoveries that explained why it is not possible to connect a smartphone to an WM100 when both devices were on the same wifi lan network, but the network was not connected to the internet.
Turns out that the WM100 and the WM100 each only communicate with the internet. Somewhere out there is a server that connects the app user to their specific hub using an internet ip address. You can see this if you turn your phone's Wifi OFF, and have the ability to connect to the internet using your phone's Cellular Data connection. With no Wifi connection, your phone will connect to the WM100 immediately.
Good news is that you don't need to do any special backflips such as tunneling or port manipulation to communicate with the hub when you are away from home ...from anywhere in the world. Unanswered question, are there any threats by the WM100's direct internet link or by the possible existence of a routing server on the interenet somewhere in the middle?
Has anyone done a traceroute on either the app's or the WM100's communications? (It's on my bucket list, but will be a while)
Another question is if there is a routing server, who's responsible and if the server is attacked or taken off line, Will WM100's then be inoperative?
fwiw, I'm currently working on the possibility of accessing 2 WM100's with one phone ...not there yet, but, I'm hopeful.
Finally, for this first post, a "don't do" WM100 tip that bit me this morning.
I was experimenting with the WM100's ALL ON/OFF options earlier when things simply stopped working. Unlike the X10's bit transmission schema where ALL ON/OFF applies only to a single house code, the WM100's ALL ON/OFF applies to all of the device codes that are stored in the HUB. Since I have three housecodes here and one of the housecodes is for devices that I never want turned off by an ALL OFF so it took me a while to figure out why there was no internet.
My internet modem and wifi are on an X10 module so I can cycle it remotely when necessary ...not something you want to turn off if you are halfway across the country.
