I would like to turn cellular on/off on schedule to save power on battery operated device, can this be done using the ethernet link connected to the modem
Hi and welcome to Digi Forum.
You can bring down the PPP interface off/on by CLI (so via local SSH/telnet connection for example) using the following commands (that will also disable the always on mode otherwise it would automatically re-connect again):
ppp 1 aodion 0
ppp 1 autoassert 0
ppp 1 deact_rq
config 0 save
To bring it back up, the commands would be:
ppp 1 aodion 1
ppp 1 autoassert 1
ppp 1 act_rq
config 0 save
(this will also re-enable the always on mode, depends on your needs of course)
The above suggestions should help in turning the Cellular connection off/on manually via CLI, but there is also another option specific for power saving that is to configure a “power control profile”.
At startup, the router always uses power control profile 0 unless otherwise configured, so basically you can configure a power profile that disable the cellular modem (and maybe other options basing on your needs) and just enable that profile by CLI.
