Interesting, surprising they are letting people profit from building units.
Wow, that's cool they're offering that! Trip - this is definitely a "niche" market that they're smart to capitalize on. The vast majority of their customers (including me) want "off the shelf, plug and play" technology - which they have. If you can make a buck or two off of the super-Q nerds (no offense to any HeaterMeter guys!), why not? This is a project I would never undertake, but might be interested in a "plug and play" version! Personally, the Auber PID is all the technology I require, but I totally respect those that want more, and the HeaterMeter seems to be the solution!
