I'd think IoT-related services (especially an entire gateway) would have years-long deprecation schedules, not a single year. If you coupled your product to cloud-based updates only (no companion app stuff), then this means your unsold inventory right now has a timer to be sold until it's dead and requires shipping back for manual updating.

Also means it's price should get discounted for that swapping out, and for "essential" stuff, like the things you stock spares for, your customers will have to go through two cycles of swapping.
