I just got 5 wireless temperature and humidity sensors, 4 out of the 5 seem to be working great. But number 5 randomly stopped sending data after I deployed it in the environment.
I can put it in config mode and alpha station sees it, i can update the config and that’s it. After i do a reset or a power cycle it never shows up again until i put it back in config mode. My gateway never gets packets and the usb modem i have never sees it in the alpha station screen that lists the sensors and packets received.
I double checked batteries, they all tested good. i also tried putting different batteries in. The xBee antenna wire seemed loose on the inside, so i tightened that all up. Nothing has changed.
Any ideas? I haven’t don’t anything radical with these sensors, i changed the timer to run every 30 minutes and wrote a custom MQTT app to read from the gateways. I would assume these things should just work.
