 CHANGELOG - towerops-web
 ========================
 
+2026-02-11 - fix: handle "null" string values in SNMP parsing
+  - File: lib/towerops/snmp/profiles/base.ex (parse_integer/1, parse_float/1)
+    Added explicit handling for "null" string values before attempting integer/float
+    conversion. Some devices (e.g., AirOS 8.7.14) return the literal string "null"
+    for unavailable metrics like UCD CPU stats, which caused ArgumentError when
+    parse_integer/parse_float tried to convert them. Now returns nil, which gets
+    coerced to 0 by the || 0 fallback in the calling code.
+
 2026-02-11 - fix: deduplicate sensors with leading-dot OID differences
   - File: lib/towerops/snmp/profiles/dynamic.ex (deduplicate_by_oid/1)
     Normalized OIDs by stripping leading dots when grouping for deduplication.
