## Overview

- Boards can be purchased directly from LilyGo on [AliExpress](https://www.aliexpress.com/item/ESP32-WIFI-Bluetooth-battery-soil-Moisture-Senson-DHT/32815782900.html)

## HiGrow's Officially Supported Repo
- Luca's officially supported repo is located at https://github.com/mongoose-os-apps/lilygo-higrow-soil-temp-humi-sensor, please consider supporting his work over there.
- Set your device `bt_devname` in the **mos.yml** file. In order for it to work with the HiGrow app, each name should start with "Higrow". According to HiGrow, this will be fixed in a future release.
