There is no specific information readily available about the exact frequency at which Rimio01 updates firmware. However, general industry practices suggest firmware updates tend to occur mainly when there are major version upgrades, specific issues, or security vulnerabilities to address. This could range from every few years to updates triggered by particular needs rather than on a fixed schedule. If "Rimio01" is a specific device or brand, firmware update frequency would best be determined through the manufacturer’s update policy or support resources. Generally, firmware updates are done:

• During commissioning or first installation,
• When troubleshooting particular problems,
• To add required new features,
• Or to address security vulnerabilities.

Regular updates help maintain performance, security, and compatibility, but updating "too often," such as quarterly, is usually unnecessary for most hardware unless otherwise recommended by the manufacturer.
