Re: Collect data from ESP on SD card in router

What's wrong with sending the sensor data from the ESPs, via MQTT with a rule-set, to a Raspberry Pi running Node-RED ??
You can then do all sorts of things with the data... store it on the Pi's SD card (local file), write it to a database (local or remote) or send it to other places.
