I bought a $60 weather station from Amazon where the base station generates a JSON file which it then wants to send to its own cloud servers. I firewalled it on its own, and have an ESP32 reading the JSON file off it and then sending the individual sensor readings into Home Assistant for a visual dashboard, and into Postgres which I use for my own weather-data-wrangling (eg hasn’t rained in a couple days and no rain expected from my local weather API? turn the watering system on for the gardens)
