Techniques to provide a low capacity notification for an energy store device

A non-transitory computer-readable medium embodying a program executable by a processor of a node in a network, comprising code for:

• determining whether to initiate a voltage measurement for an energy storage device of the node based on measurement criteria that specifies a maximum number of voltage measurements within a time period;
• and
• when a number of voltage measurements taken is within the maximum number of voltage measurements within the time period:
• measuring a voltage for the energy storage device during transmission of data to the network;
• after measuring the voltage for the energy storage device, adjusting a counter for the node based on the measured voltage, wherein (i) the counter is adjusted in one direction when the measured voltage is below a voltage limit, and (ii) the counter is adjusted in an opposite direction when the measured voltage meets the voltage limit;
• and
• comparing the counter to a low capacity threshold, wherein the low capacity threshold corresponds to a predetermined number of measurements below the voltage limit in excess of a number of measurements that meet the voltage limit;
• when the counter meets the low capacity threshold:
• determining that a low capacity condition for the energy storage device exists;
• and
• transmitting, via the network, a notification for the low capacity condition of the node;
• and
• when the counter is below the low capacity threshold, storing a value of the counter for use with a next voltage measurement.
