Release 5.2

• Handle Smart Power level changes while in monitor mode.
• Add support for boilers that generate unsolicited Medium/High power.
• Limit the validity of a CS command. A remotely set control setpoint expires after just over a minute. This is a safety feature to prevent runaway heating when the controlling program loses its connection, or crashes.
• Change the default voltage reference to 1.458V (4), which translates to a line voltage that lies closer to the midway point between the high and low voltage levels defined by the Opentherm specification.
• Change the voltage to detect a disconnected thermostat to 20.05V. The old value of 19.11V might give false positives due to component tolerances.
• Pass on the response for MsgID 9 and MsgID 100 from the boiler (or a downstream gateway) if it is a Read-Ack or Write-Ack and the OTGW doesn't have any active override itself.
