Scripts for extending SNMP on Asuswrt-Merlin routers to include the following values:
- CPU temp
- DHCP leases
- Connected clients
- 2.4GHz radio temp
- 5GHz radio temp
- Memory used
- Idle CPU
- Uptime
- Partition use
- WAN traffic up
- WAN traffic down
This has been tested on ASUS RT-AC68U and RT-AX86U. Other devices may require tweaks to scripts. Pull requests are welcome.
This was created for Home Assistant users wanting more stats than provided by the ASUSWRT integration or who wish to track multiple ASUSWRT devices, as the integration is limited to one instance. It should of course work with any platform with SNMP support.
- Asuswrt-Merlin firmware installed
- SSH enabled (during installation)
- JFFS scripts enabled
- SNMP v2 enabled
- SSH to the router
- Create an snmp directory in the jffs scripts directory
mkdir /jffs/scripts/snmp/ - Copy all script files into the snmp directory
- Copy the file
snmp.conf.addto/jffs/configs/directory - Restart SNMP (disable/enable) or reboot the router
- (optional) disable SSH
Technically everything is returned as a string but the string type is defined below. All results are returned as raw data without units symbols.
