Feature Request: 3rd party cellular modems

[kwschnei]

Have you considered adding 3rd party cellular modems/routers? I'm sure that I'm not the only one running a GL-iNet router.

You can run AT commands against the router via SSH, so I'm not sure how difficult this would be to integrate with what you're doing for the UniFi routers already. Running the following command returns everything that should be needed on my three GL-iNet cell routers (Mudi v2 [E750], Spitz AX [X3000], and Puli AX [XE3000]). If there turns out to be model differences in the command, the command prompt actually returns the model number.:

gl_modem -B 1-1.2 AT AT+QENG="servingcell"
