@jimbolaya Sorry, link is now fixed.

@jimbolaya Something like this should work: http://www.digikey.com/products/en?keywords=IPP055N03LGXKSA1-ND.

@dbemowsk Thanks for posting. Mine are the 8 color variety which I think they likely accomplish by mixing 3 colors. I'll have to dig up the non-working one and take it apart to take a look.

@dbemowsk Yes, I do have the power supplies. They are 7V AC rated for 5A:

I've never seen 7V power supplies before, so probably not easy to find. Is there a 5V regulator on the board?

I've never been able to find any schematics for them. I have one that doesn't work as well, but have not taken it apart yet.

Looks like a betabrite sign. I use some with HomeSeer to display weather info, sports scores, etc.

@Cliff-Karlsson That should work, but I would try using tape first so that it is easy to readjust. Once you have it adjusted the way you want, then replace the tape with paint.

The RFXCom receivers also support the Maverick ET732 and ET733 BBQ Thermometers and the Oregon Scientific AW129 and AW131 thermometers. I currently use the AW129 but am also interested in a dual probe thermometer that can control a fan.

Here's one on AliExpress that can do 200 l/m: http://www.aliexpress.com/item/YF-DN50-2-inch-Large-diameter-turbine-flow-meter-water-flow-sensor-industrial-flow-meter-Available/32297810863.html?spm=2114.40010208.4.71.i72mzF. Not sure if I would trust it though.

@ericvdb

They are available, but not cheap. Here are some examples for the North American market: http://www.jerman.com/dljcmeters.html.
