Thanks for this. I found an error in a node, which was causing an error with my table, which was formatted exactly the same as yours.
In the "insert" node after "Check Page",
var query = "INSERT INTO responsetimes(deviceId, displayName,
value) VALUES(";
query += "1,";
query += "'Hubitat Elevation Hub',";
query += "'" + msg.responseTime + "'";
query += ")";msg.topic = query;
return msg;
I think it was totaltime, in the downloaded version, and causing errors in my DB.
