I would like to suggest that cambium CNmestro has the option the schedule reboots.
Hi,
Please take a look at the following thread and answer from Rupam:

Thanks,

In addition to the one-time reboot from cnMaestro, on cnPilot E-series you can schedule a periodic reboot too if you need that for any reason:

this is a configuration item and the CLI commands for this can be pushed down from cnMaestro using device-overrides.
