Wifi of sensor is lost

I want to know the seri number of sensor have id:30:83:98:af:d0:2
I need it to setup wifi because the hostpot not appear

My WiFi lost contact with my PurpleAir outdoor sensor. I brought it indoors, right beside my router, but the WiFi was never found. I sent the unit back to PurpleAir for testing and discovered that the internal electronics for WiFi were no longer working. It appears that a power surge might have blown it. I paid for a replacement (I did not own the original for even 2 years) and installed a high quality surge suppressor in my circuit to prevent this from happening. Adding over voltage protection to PurpleAir units would be an excellent upgrade, especially considering the rapidly increasing power failures throughout the country.
