Right. You can buy a smaller number for even less. The instructable
below shows how to control it with a Raspberry Pi.<br>

<br>
But you're still going to need invention, and that's the magic that
bridges between what your packet program is doing on the Raspberry
Pi and the actions necessary to invoke the program to turn on the
Sonoff. You won't find that at Amazon Prime, but if you come to the
meeting tomorrow somebody might be able to find out more about how
the packet radio code works and suggest an approach. <br>

<div dir="auto">Hey Tadd,</div>
</div>
<div dir="auto">If you’re talking 10 years ago
time frame I’m guessing you’re referring to the
AmbientOrb. It was a device from an MIT group/project
that signaled the state of the weather, stock markets,
etc... Here’s an article about that device.</div>
<div dir="auto"><br>

<div dir="auto"><br>
</div>
<div dir="auto">There have been many of these
types of devices launched as
products/kickstarters/DIY projects since then, in
various incarnations. I’m sure you can find examples
on <a href="http://Hackster.io" target="_blank">Hackster.io</a>. Here’s one
I built:

great for this type of thing.

<div style="word-wrap:break-word;line-break:after-white-space">Once upon a time, possibly 10 years
ago, I remember a device which looked like a
light fixture that sat on a desk. It lit up in
color, after it found some token or cue on the
Internet. You could use it to show a weather
alert, or i a certain web page did or did not
responded to pings.
<div>I never bought one. Now I need it
for a ham radio project. </div>
<div><br>
</div>
<div>What I want to do is have a
Raspberry PI that is doing ham radio stuff
(TARPN network communications, in this case)
and have a light, possibly a blinking LED, in
the living room of my house, that would
indicate a message has been received via the
ham radio TARPN network. The Raspberry PI can
have a file that is present or missing, or
filled with some value or another, and the
blinking light needs to use FTP or Telnet via
WiFi to the Raspberry PI and query the file.
Alternatively I could have the Raspberry PI
issue a telnet message to turn the light on or
off. </div>
<div><br>
</div>
<div>Something like this already
exists. Does anybody know where to get one? </div>
