I am a member of a curling club that has a dedicated facility. We operate a chiller to make the ice, and every now and then it decides to turn itself off requiring a manual restart. We have a remote camera on the chiller control panel so we can look to see if it is running, but obviously we’d like some sort of automated alert when that happens. The chiller is located outside.
I’m thinking of 3 possibilities and trying to determine if we could easily do any of these 3 with smartthings.
Monitor the decibel level at the chiller. It’s quite loud when it’s running, almost dead quiet when it’s off.
Monitor vibration on the chiller. I assume there’s enough difference between running and not to trigger an alarm.
Monitor a drop in temperature of either the ice or the refrigerant lines. If either drop enough in a few hours we’d know there’s a problem.
Any suggestions on how to do any of these using smartthings?
That seems way too high. Even with industrial level controls, this should be may be $2-3k for the CT and logger. If someone knows of an analog ST input module that accepts analog mV signals, then you could read if the power is on or off and warn accordingly. Labor and wiring would add more, but not $12k.
That’s the key words! Measuring the amperage will let you know if it’s working. An Aeotec Home Energy Meter will do the trick but it’s kinda expensive. The chiller is more than likely on its own circuit and you can install the meter at the breaker. Then use webCoRE to write a rule to alert you if the wattage stays below a certain value for a certain period.
