The ZWAVE sensor is a great idea, I’m going to look at that for my sump pump in the basement. The challenge in septic tanks is the hostile gases that are created. I had an airline cable (steel cable) attached to the top of the pump to be able to pull it up, and over about 2 years the effluent dissolved the cable! This is the 2nd camera I’ve put in there; the first one died after about 3 years and when I pulled it out it was absolutely corroded and gross. Monitoring tank levels would be so much easier if it was a clean environment.
The other challenge is that it’s a concrete tank and lid. So getting any sort of wireless signal is challenging. For my camera(s), I’ve ended up using extension cables on the wifi antennas to bring the antenna’s up out of the lid. Outside the lid they can get signal easily.
