Cesar came out this morning with his sidekick. They replaced the furnace draft butterfly valve. It doesn't really draft much when the furnace is running. I doubt if that's going to control humidity. I'll leave the humidifier running for a month or so to let the wood dry out.. It's been sitting at 90% humidity practically forever. This should help big time. They also tightened the fitting on the sump pump that was leaking. After Clarinet practice I finished wiring the sonar to the Huzzah I think. Need to test it. The relay is not here yet, maybe some day next week. I also researched current sensing and ordered some magnetic current clamps and also an A/D converter breakout. With a little code I should be able to monitor the Sump pump on/off cycles, the dehumidifier on/off cycle and the furnace on/off cycle. For the furnace I can put the clamp inside the unit. Both the Sump pump and the dehumidifier will need the probe inside an electrical box. I took a walk around Seagroves Farm Lake today and home. I estimate it's around a mile. It's near 90 today the way I like it but I was surprisingly tired from the walk.
