Thanks for the inspiration.I am also playing around with this board, trying to get something out of it and to learn. I will try to give you two answers to your questions from my experience. Regarding "deep sleep", I have read a lot and also measured, and it is not impressive on this board. Minimum 3 mA in deep sleep. I have therefore made another solution, where I use an Attiny85 to turn on/off the ESP32, and the Attiny85 use almost nothing when sleeping. I want to make an instructable one day, but it is with an Attiny85, TTGO ESP32 LoRa board, a P-channel MOSFET and NPN transistor, with a 3,7 V battery. Regarding data into a database, I have setup a local SQL db, where you can connect from your Gateway "Receiver" on WIFI to SQL. (MySQL_Connector_Arduino Library). This…

Regarding data into a database, I have setup a local SQL db, where you can connect from your Gateway "Receiver" on WIFI to SQL. (MySQL_Connector_Arduino Library). This way you can send from multiple "Senders" to the gateway/receiver, which inserts to the database. Then I use Grafana to show the data. I think that is a neat local setup. I have also tried TheThingsNetwork, and you connect with the board, but I think it is too complicated and overkill for local setup.Good luck! // Mikael
