Can we see EXPLAIN output of the following SQL please?

EXPLAIN SELECT SensorTime,Value FROM RemoteStatuses WHERE RemoteID = X AND DataID = Y AND SensorTime BETWEEN A AND B \G

You may convert this table to InnoDB, primary key would be used a clustered index. Accessing a row through the clustered index is fast because the row data is on the same page where the index search leads.

What version of MYSQL are you using?
