Hi, from a brand new poster. I have a farm water pressure system in a shed, mostly watering troughs for stock. When there is a slow or fast leak, I waste water, at expense. They could be broken valves to pin holes in pipes. The pressure is system is run by 240V mains, (Australia) via a plug into a socket, as normal. There is a smart meter in the shed. Stock generally don't drink much from midnight to 5am. If there is a constant leak, the pressure system will cycle during the night. What I want to know is, is there a way to trigger an indicator that shows the pressure system is cycling overnight between set hours (12 - 5am)? Eg, a few cycles may be acceptable, 5-10 are not. When noticed, I can go to the shed, further investigate, and reset the trigger. I also have capacity to read water pressure at my house, on the same system, which will fluctuate as the pressure system cycles. If I could easily track and record the pressure fluctuations, I would also know if there is a leak. Apparently I could install a flow meter with a wifi or sms system, but that sounds expensive and complicated. I don't use a flow meter as it is not needed. So we have power usage, pressure switch triggering, water flow, water pressure , noise, and pump heat as indicators, at the pump shed. I have line of sight to the shed from my house, about 500m away. I could see any alert lights daily, both at dark in the evening, and in morning daylight. They could be 240V or battery powered. I am currently tapping into the pressure switch to run a light. The problem is 1. I have to be awake then to check a light. 2. it takes time for long cycles to occur. For all I know there may be something available already, which I have not yet found. I don't have need, yet, to be alerted as an absentee manager (eg sms alert). I know there are fancy systems available for sale for that. Any technical ideas would be most welcome, thanks, including combinations of the engineers parameters - cheap, strong, quick.
