summary

Shows how to collect continuous temperature and relative-humidity readings from sensors attached to a Raspberry Pi using Python, then forward those readings through syslog-ng into Elasticsearch/OpenSearch. Explains a syslog-ng limitation and the configuration workarounds on both the syslog-ng and Elasticsearch sides, and demonstrates visualizing the data in Kibana plus practical tips for keeping room humidity low.
