RKE updated

After determining that the RKE head unit was corrupt, I sent it in for repairs. It somehow got fried after I did the firmware updates. Who knows what did it? But, it wasn't too much of a loss for me since I actually got the free V2 head unit trade-in when it was available back when. So, I went ahead and purchased a replacement unit and it's been up and running since May 3rd.

With the NET module working, I was able to look at the data that's been recording. Temperature reflects San Diego weather that affects the house:

The pH is fluctuating with lights on/off as it should (a spike marks a water change):

I still haven't bothered calibrating ORP since I don't really use it to push the tank in either direction. The spikes correspond to the water changes that are done once every 2 weeks. The ORP is inversely related to the pH.

The data are not uploaded to any website just yet since the router I'm using is not able to act as an access point. I'll have to search Craigslist for some old router or get a fancy Airport Express that I can hook up to a sound system and listen to Airtunes for my big fat Airhead.
