luci-mod-rpc: net.arptable - Method not found

Hi all,

I want to use Home Assitant’s OpenWrt plugin to track devices (Wiki, source code). This plugin uses luci-mod-rpc to retrieve the arp table, and uses them to track devices. However, issuing the rpc call gives me a “method not found” error: curl http://192.168.111.XXX/cgi-bin/luci/rpc/sys?auth=AUTHTOKEN --data '{"method":"net.arptable", "params":[]}' {"id":null,"result":null,"error":{"message":"Method not found.","code":-32601}} Other call like net.ipv4_hints work perfectly. Does anyone know whats happening here?

Regards, Alex

I have same question with you, I find the openwrt_luci_rpc.py files in home-assistant deps folder has lines:

if self.owrt_version < version.parse("18.06"):
            return True, rpc_sys_arp_call
        else:
            return False, rpc_ip_call

It seems to obtained a wrong version? because I used koolshare fireware. when I comment those lines and append:

return False, rpc_ip_call

It works!

Trouble is that many OpenWRT-based firmwares use their own version scheme. I use TurrisOS 5.2.5 which is based on OpenWRT 19.07 but openwrt_luci_rpc.py thinks that the version is 5.2.5 and hence “legacy” 😦
