postgres=# \c timeseries
timeseries=# CREATE EXTENSION IF NOT EXISTS timescaledb CASCADE;

Create a table:

timeseries=# CREATE TABLE conditions (time TIMESTAMP WITH TIME ZONE NOT NULL,device_id TEXT,temperature NUMERIC,humidity NUMERIC);
timeseries=# SELECT create_hypertable('conditions', 'time');

Insert data:

timeseries=# INSERT INTO conditions(time, device_id, temperature, humidity) VALUES (NOW(), 'weather-pro-000000', 84.1, 84.1);
timeseries=# INSERT INTO conditions VALUES (NOW(), 'weather-pro-000002', 71.0, 51.0),(NOW(), 'weather-pro-000003', 70.5, 50.5),(NOW(), 'weather-pro-000004', 70.0, 50.2);
