Mesh network connection quality

A system comprising one or more computers and one or more storage devices on which are stored instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:

• transmitting, by a control unit of a monitoring system that is configured to monitor a property, test data to a first connected component of the monitoring system;
• in response to transmitting the test data, receiving, by the control unit, response data from the first connected component of the monitoring system;
• determining, by the control unit using the response data, a number of different unique routes a) used to transmit the test data to the first connected component and b) that each include two or more nodes, the combination of the two or more nodes for each of the unique routes being different than a combination of two or more nodes for any other of the unique routes;
• generating, by the control unit and using a value indicating the number of unique routes, a link quality indicator that reflects a strength of a connection between the control unit and the first connected component;
• and
• based on the link quality indicator, adjusting, by the control unit, one or more settings of the connection between the control unit and the first connected component.

A non-transitory computer storage medium encoded with instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising:

• transmitting, by a control unit of a monitoring system that is configured to monitor a property, test data to a first connected component of the monitoring system;
• in response to transmitting the test data, receiving, by the control unit, response data from the first connected component of the monitoring system;
• determining, by the control unit using the response data, a number of different unique routes a) used to transmit the test data to the first connected component and b) that each include two or more nodes, the combination of the two or more nodes for each of the unique routes being different than a combination of two or more nodes for any other of the unique routes;
• generating, by the control unit and using a value indicating the number of unique routes, a link quality indicator that reflects a strength of a connection between the control unit and the first connected component;
• and
• based on the link quality indicator, adjusting, by the control unit, one or more settings of the connection between the control unit and the first connected component.
