Hi Neziak,
on an Iridium Go there are a number of things I would do to reduce unnecessary data usage:
- Disable healthcheck on WIFI WAN - you don’t want to waste bandwidth checking its available
- Create general internet rule - Create an outbound policy (lowest latency) and include all WANs apart from WIFI WAN (which is connected to the Iridium). Make sure ‘Drop the traffic’ is selected for this rule so that WIFI WAN never gets used for general internet access.
- Let predictwind use WIFI WAN - Create an outbound policy priority rule for forecast.predictwind.com that prioritizes all other WAN links first then WIFI WAN last, put this above all other rules.
- Iridium email. You’d need to do a littl ebit of detective work to find out what servers they use for email. Once you have those (IPs or DNS name) you can then create another rule for that and add it above the predictwind rule above.
Good luck! Shout if you need any help.
