After an internet outage, I had the ISP tech come by to manually reboot the router. My wifi connections to my HONEYWELL THERMOSTAT , NEST SMOKE DETECTORS AND BLINK CAMERAS all came back online. however, the Acurite 0915M (purchased April 2018) did NOT....flashing RED light. Removed the batteries, unplugged the AC adapter and removed batteries for 60 sec. Reconnected all and the light still blinking red...NOT STEADY BLUE! what do I need to do?
