Motion Sensor with very many updates causes Lovelace / Chrome to hang

Hi folks,
I have PIR Motion Sensors which generates a very large number of state changes each day. When clicking on the sensor in Lovelace and it displays the histogram and update log the UI will hang and HA becomes unresponsive for about a minute. What’s a good strategy for dealing with such active sensors? Are there options in Lovelace to somehow conflate or truncate the number of updates displayed on the entity card? Thank you

Was the sensor discovered or does it have a yaml config?

The sensor was discovered by the MQTT integration.
Actually I am using an alarm add-on (https://github.com/dchesterton/texecom2mqtt-hassio), this interfaces with our home alarm system and reports state via MQTT to HA.
