## Connection Refused Errors
From early 2022 Heatmiser introduced NeoHub firmware that has the ability to enable / disable the NeoHub `portNumber` 4242.
If this port is disabled the OpenHAB binding cannot connect and the binding will report a *"Connection Refused"* warning in the log.
In prior firmware versions the port was always enabled.
But in the new firmware the port is initially enabled on power up but if no communication occurs for 48 hours it is automatically disabled.
Alternatively the Heatmiser mobile App has a setting (Settings | System | API Access | Legacy API Enable | On) whereby the port can be permanently enabled.
