pesor / TTGO-T-HIGrow

The extremely good plant sensor named LILYGO TTGO-T-HIGrow, is here integrated into Home Assistant, via MQTT messages, that can be Autodiscovered, via the belonging Python program. The program supports both DHT sensors, the new BME280 sensor and the external soil temperature sensor.

external PT100 sensor #5

Closed elecoq129 closed 3 years ago

elecoq129 commented 3 years ago

the idea is to make use of of the external I2C UART port, adding support for DS18b20 sensors would be really useful for measuring the temperature of the soil rather than the air temperature that the integrated sensor measures. As current firmware does not use, could you please implement it?

Thanks & Regards

You can add an external sensor to the I2C UART port. I think the PT100 is just an external waterproof DS18b20 temperature and humidity sensor. https://www.aliexpress.com/item/4000402593081.html?gps-id=pcStoreJustForYou&scm=1007.23125.137358.0&scm_id=1007.23125.137358.0&scm-url=1007.23125.137358.0&pvid=4fb3238d-4436-414b-b158-76a9fd96801b&spm=a2g0o.store_home.smartJustForYou_237836912.7
