InfluxDB measurement limit?

I’m using influxdb in combination with Openhab to store sensor readings. 1 reading every 10mins. For visualization I’m using Grafana. When I installed a new sensor I noticed that the readings of the old measurements were not shown. So I set the Date Selection 2 months back and saw that the readings stopped being written. Is there a limit of entries per measurement?

No there is not (assuming you are using the default retention policy which is INF)
