Wireless sensor diff alert

Hi.

I have a bunch of wireless links in LibreNMS (ptp links)

I want to know if its possible to create an alert if the signal strength changes. Obviously some links have different RSSI value to others so a blanket “high” and “low” will not help. I want to know if I can have an alert if the value changes ±10 either way? Is this do-able?

You should be able to configure the High and Low values per device in device settings. Then just use the alert in the alerts collection sensors under the limit or over limit rule.

Perfect. Thanks!
