Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
The relay itself doesn’t matter especially given the fact that it’ll be on/off only, so I’d recommend a Shelly Plus 1 flashed with firmware to get it into HomeKit incredibly easily. The contactor doesn’t need to be anything fancy, just needs to be rated appropriately for the load at hand!
