The Room Alert 3S internal temperature sensor plugin (introduced in Werk #19562) only fetched the Celsius OID from the device. On some hardware configurations, direct SNMP walks do not return a Celsius reading, causing the Room Alert 3S Temperature service (item: Internal) to produce no data.

The plugin now fetches both the Celsius and Fahrenheit OIDs. Celsius is preferred when available; Fahrenheit is used as a fallback so that the service continues to report the internal temperature correctly.
