[RE-wrenches] Enphase and Quantum Fiber

[Zeke Yewdall]

A lot of inverters (and other monitoring equipment as well) will only
connect to a 2.4GHz wifi.  And more and more ISP's are providing routers
that default to 5Ghz, or a mesh network.  If it's my own, I go in and turn
off the 5Ghz (or at least add a 2.4Ghz) usually as 5Ghz is actually worse
performance than 2.4Ghz for ISP's under about 200Mbps speed, in my
opinion.

But what I think is best practice for installs, and what I've tried to
start doing, is add a 2.4Ghz router specifically for IoT things, like
inverters. That way, when the customer gets a new ISP with a new ISP
provided router, all you have to do is reconnect the IoT router to the ISP
provided router (either with a hardwire cable, or programming the IoT
router to rebroadcast the new ISP wifi).  Instead of having to go through
possibly dozens of different IoT devices and reprogram them all to a new
wifi SSID and password.  If you do this, you should probably put a label on
the IoT router so the customer doesn't throw it away though... I've had
them do that when they clean up their office, they don't know what some
piece of equipment is, and throw it out.  Had many of them do that for the
ethernet over powerline adaptors for the earlier egauge units, then call me
up to ask why their monitoring didn't work any more -- and being an
obsolete adaptor, you couldn't even just buy a replacement.
