Tim Fitzpatrick Posted June 18 Share Posted June 18 I have made in the past with an ESP, an auto on vacuum. With the ESP I need to add a current sensor and power source for the ESP. It work ok, just not great. The purpose is to turn on a small shop vac when a tool is turned on. Example; When a chop saw is turned on and the Shelly senses current flow, then it turns on a shop vac. I was thinking something like the attachment. Thanks in advance for your input. Tim Auto Vac.pdf Quote Link to comment Share on other sites More sharing options...
