snmpwalk -v 3 -l noAuthNoPriv -u admin [IP address] 1.3.6.1.4.1.20916.1.14.1.1.1.2<\/pre>\n\n\n\n
… returns values such as:<\/p>\n\n\n\n
sensorsName.0.190.68.234.63.223 = TH-3FDF <\/pre>\n\n\n\n
- \n
- If your sensor labels have not been customized, you can match the default labels to their MAC address based on the returned value (TH-3FDF matches up to a MAC address ending in 3F:DF).<\/li>\n<\/ul>\n\n\n\n
- \n
- If you have access to the device’s web interface, you can match the MAC to the corresponding sensor card. (See How To Open Your Room Alert Monitor\u2019s Built-in Web Interface<\/a>.)
![\"\"](\"https:\/\/avtech.com\/articles\/wp-content\/uploads\/2026\/04\/image.png\")
<\/li>\n<\/ul>\n\n\n\n- \n
- Otherwise, you can match the sensor labels to their MAC by getting the HEX value of the returned index.<\/li>\n<\/ul>\n\n\n\n

<\/span>Working with individual OIDs<\/div>\n\n\n\nIf you need to work with individual OIDs, one method is to walk the entire device and then pull the results into a code editor capable of highlighting matches (or “highlighting all occurrences”) such as VS Code. This way, you can highlight a sensor index, or part of a sensor index, and see all matches.<\/p>\n\n\n\n
