Hi,
I suspect I’ve got the same issue.
I’m receiving data over MQTT from some remote sensors. The data is in float form (XX.YY) and represents Temp, Humidity and Heat Index (a further topic also sends Barometric pressure [XXXX.YY]). The periodicity of traffic bursts is governed by a change in the ambient variable. ie. a delta in temp will trigger an MQTT publish.
Potentially, once scaled up this could mean many asynchronous updates over MQTT.
I’ve noticed from my tailed debug the update occurs when such an MQTT publish happens bearing out what frederic0 states.
So far the only way I’ve found to minimise the refresh impact is to bury the individual charts under some sub menus.
Would love to hear of a fix if one is out there
