Heartbeat is the interval (in minutes) between a sensor’s regular check-ins. Shorter heartbeats mean more frequent messaging and higher daily power use.

What are Readings per Heartbeat?

Some sensors take multiple measurements each heartbeat before transmitting. Increasing readings per heartbeat can raise daily energy consumption.

What do Good Signal and Low Signal mean?

Good Signal is typically 50% or greater signal strength; Low Signal is 25% or less. We model higher transmit energy per message in lower signal conditions.

Q: How accurate are the estimates?

Results are modeled from engineering profiles and typical conditions. Actual battery life varies by environment, battery quality, and usage. Some batteries are display-capped for conservative guidance.

Signal guidance

"Good Signal" means ≥ 50% signal strength.
"Low Signal" means ≤ 25% signal strength.
Lower signal generally increases transmit energy per message.
