The frequency of updating the firmware of your IoT device depends on several factors such as device type, functionality, security risks, and user expectations. Here are key points to consider:
- Update as needed for issues or security patches: Update your device firmware when there are known issues or security vulnerabilities. Regular updates patch known vulnerabilities and improve encryption and authentication protocols, which are critical for security
- Plan update frequency strategically: Devices with complex functions or higher security risks (e.g., smart thermostats, smart locks) may require more frequent updates than simpler devices like smart light bulbs. User expectations also influence update frequency—some prefer stability with fewer updates, others want the latest features
- Typical update cadence: For many devices, firmware updates are shipped about once or twice a year if the device is relatively new, balancing stability and improvement
- Best practice is to monitor and evaluate updates: Deploy updates gradually (canary deployment) to a limited set of devices first, monitor performance and KPIs, and only roll out broadly if no issues arise
- Use Over-the-Air (OTA) updates when possible: OTA updates simplify the process and allow timely deployment without physical access
- Backup data and ensure stable power before updating: To avoid data loss or update failure, backup critical data and ensure the device has sufficient power during updates
In summary, you should update your IoT device firmware regularly but not necessarily on a fixed schedule. Instead, update promptly when security patches or important improvements are released, plan updates based on device complexity and risk, test updates carefully, and deploy them in stages to avoid widespread issues
. For many devices, this translates to roughly one or two updates per year, with additional updates as needed for security or functionality
