You are correct. It is an old thing. And no sign of new money. I however am
not interested in retro fitting water meters. And I do not have a company
whose sole interests is in reading meters. I simply enjoy finding technical
solutions for problems. And it keeps me in the air conditioning during the
summer months. I did a custom system in Louissiana a few weeks ago. I used
rs485 and a lot of cat3 wire. It seemed easier to do it that way. And it did
work very well. But it took too long to bury the wire. Or tack to the walls
where I could. SO I decided to use radio for the next one. Bit of a pain. It
seems all of the radio modules are made over seas. And if you want less than
a 1000 nobody is interested. I believe I have found something that may work
and I have ordered the developers kit. I'll know when I have returned to
Florida to test it.
