LilyGo HiGrow ESP32 Plant Monitoring Sensor with MQTT

Firmware for Hardware v1 (without light sensor).

This is a fork of https://github.com/mongoose-os-apps/LilyGo-HiGrow-Sensor-v1.git. Added MQTT and power saving features.

Differences

• This codebase focuses on the v1 hardware, which does not have a light sensor.
• RPC support included
• Device id's are not tracked and sent to HiGrow's cloud at https://api.higrow.tech/api/records
• MQTT support added
• Configurability of frequency of measurement
• Bluetooth made optional
• Power saving mode (deep sleep)

Overview

• Use this code with MongooseOS and the LilyGo HiGrow ESP32 Plant Monitoring Sensor v1.0 board to obtain sensor readings and control LED's
• Boards can be purchased directly from LilyGo on AliExpress

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.
• Visit http://www.higrow.tech/en/ more info on the HiGrow project.

config_schema:

• ["higrow", "o", {title: "LilyGo HiGrow ESP32 Plant Sensor v1 App Settings"}]
• ["higrow.deviceId", "s", "", {title: "DeviceId"}]
• ["higrow.send_mqtt", "b", true, {title: "Send data using MQTT"}]
• ["higrow.send_http", "b", false, {title: "Send data using HTTP"}]
• ["higrow.send_http_url", "s", "http://example.org/what/ever", {title: "Send data using HTTP"}]
• ["higrow.sample_time", "i", 300, {title: "Take a sample after that amount of seconds"}]
• ["higrow.wait_after_last_action_before_sleep", "i", 10, {title: "Wait this number of seconds before we go into deep sleep"}]

To change the configuration it is recommended to use either UART or MQTT communications.
