I am looking for ways to send bulk sensor data represented in a JSON format or in a .csv file to HA. Let me explain the situation a little bit. I have some weather sensor data (temperature, humidity, air pressure, all connected to a collection time stamp) which is collected continuously with a low power micro controller. In order to save power and make the remote micro controller long lasting, it should send the collected sensor data only twice a day as bulk to Home-Assistant via Wifi. How could I achieve this in Home-Assitant so that the bulk data are received correctly and filled in the HA database with the correct collection time stamp?
A rather similar situation with an other IoT product is posted in this blog article "Send Bulk Sensor Data to ThingSpeak for Analysis ".
Thanks in advance for some hints,
