I had my original issue wifi boards set up and working for several months. Then they stopped communicating with the hub Through the Smartthings app, going to Automation/smartapps/Konnected i see the two wifi boards for my system, but when i select then to see the device status the page is blank. I have the Smart things hub plugged into my router in my first floor, and my security panel is in basement straight line distance 20'. I have the front door off my security panel where the boards are mounted. I was not getting strong signal from wifi based on free app WI-Fi sweet spot, so i added a wifi extender and then connected boards to that. I thought wifi boards went bad, possible lightning or some surge. Got new wifi boards and installed, added them to network, and they showed up in the konnected smart app under device status for a short time, now device status screen is blank again and in the smartthings app under My home/things devices are not updating. I have a wireless Smarthings water leak sensor which is farther from hub that is working. I assume wifi boards may be loosing wifi signal and not reconnecting. I have spent hours trying to figure this out. need help.
