If I configure the 8266 module to connect to my home WiFi, will it afterwards automatically connect each time it's powered up, or does some serial command
need to be sent for it each time to connect?
If it connects automatically on powerup, then one can use it as a super-simple wireless sensor (with significant latency, but that's irrelevant for my
application). I'm thinking of using it in conjunction with a Leakfrog water leak detector. The idea is that I would wire 8266 modules to Leakfrog units, so that
when a water leak is detected the 8266 is powered up, and connects to WiFi. Some other device running on my network (e.g., an old Android phone or
tablet, or maybe a router with custom firmware) will be polling the network and will email and text me to tell me which 8266 module has powered up, and will
again email and text when the module has powered down.
But if the 8266 requires a serial command to connect, then a microcontroller is needed to generate that serial command, and that complicates the hardware.

it doesn't need to be reconfigured. once set, it will connect automatically each time the system is powered up.
and yes about the super simple wifi sensors, check this out; http://www.esp8266.com/viewtopic.php?f=8&t=390
and ther is no latency. I watched my DHT11 upload to thingspeak using ESP, live feed, very smooth.
we are working on getting simple analog sensors online and even e-mail/txt you once they are triggered..

Sounds great! I want to run it without any processor attached--just have it fire up when the signal fires, and then have something else on the WiFi
network pick up the IP address. This way, the costs per unit are low (I want to do four units) and it's real simple.

something called an SDK attachment for the ESP, which i believe eliminates the need for an arduino.. i don't know what it is exactly, i'm not
experienced enough.. you should check out the above useful links for sure, especially the forum !!

That's super-cool.
Do you have any actual numbers on the latency? For another application (wireless foil/epee fencing equipment), it would be really great to
have something with latency, in the 1-2 ms range.

i'm going to say that it is more like 3-5ms when it comes to uploading to thingspeak.. on the data sheet it mentions 1-2ms from boot up to
send data BUT there are lots of obstacles here. i'm sure you can cut the time down to 1-2ms if you didn't use thingspeak but maybe your
own server?! it connects to the wifi network only 1 time as well, only at boot up. afterwards it stays connected until turned off.

Nice introduction! Are the GPIOS that do not have breakouts on your version accessible to a skilled solderer by tying in to the chip pins?

I think that is too tiny to solder to. Well at least for me. But they are accessible.
