My customers would open the doors and leave them open, this year I put "do not open bay doors" sign on them and I don't think I had one person open and leave open.My customers can open entry and exit doors. They close doors behind them to escape wind or bad weather, most have learned to close doors n winter upon exit. I have a weep system and heated floors,other users usually close a door if left open by others. I do keep posted hours 6 am to 8 pm and its gated. 20 years like this and don't recall any issues.
This is the info I’m looking for thank you!I bought a 4 relay USB relay board by Denkovi for about $35 (check eBay). It allows me to close 4 different relays via the internet.
You could use this device to open/close your doors if you have door operators.
The Denkovi device connects to the PC at my car wash, via USB. I access the car wash PC remotely using RemotePC. Remote PC works with Windows, Apple or Android.
