I purchased 2 (one for a spare) WiFi Relay Controller with High Power Relays with WiFi communication and am having a problem with both of them.
The controller is mounted in a plastic box with two 2.5" vents and a fan under my porch and I’m communicating with it via Visual basic using the NCD .dll.
I have a strong WiFi signal on the porch. The access point is on the other side of the wall.
Everything works fine, but every day (seems like only during the day), the controller becomes unresponsive both to my VB program as well as the NCD Base.
I have to power it down and back up to get it to communicate again.
The controller box is sheltered from direct sunlight as well and doesn’t seem to be more than slightly warm. The only other things in the box is a current transducer and a small DIN mount 12vdc supply.
I’ve tried changing the UART Delay between TX Bytes and the UART RX timeout but doesn’t seem to matter where I set them.
