+## Database correction
+
+Sometimes getting wrong data from my smart meter, that one have to fix in database with the SQlite Web add-on on my home-assistant instance, with following commands:
+
+```sql
+SELECT *
+FROM "statistics" WHERE CAST(mean AS DECIMAL(12,6)) LIKE '3976%'
+
+UPDATE "statistics" 
+SET mean = OtherTable.Col1, 
+    Col2 = OtherTable.Col2 
+FROM (
+    SELECT *
+	FROM "statistics" WHERE CAST(mean AS DECIMAL(12,6)) 
+	LIKE '3976%')
+```
+```
