This project is no longer supported, it was build at a time when there was no official supported Gardena API. By now there is a new implementation, with realtime interaction and supporting all gardena devices:

https://github.com/py-smart-gardena/hass-gardena-smart-system

Custom component to support Gardena smart devices, all device will be automatically discovered. It uses a seperate library (also written by me), this library has additional (intersting) details in it's documentation: https://github.com/wijnandtop/wt.pygardena

It supports the devices:

Mowers will be added as vacum cleaners. The vacum cleaner is the closest thing to a lawn mower, it has characteristics like a base station, being a robot, supports simular command (stop, start, dock) and has battery status. Start will trigger 24h of mowing.

https://www.gardena.com/int/products/smart/smart-system/gardena-smart-sensor/967044801/ Device is registered as multiple sensors:

• soil temperature (sensor as class temperature)
• soil humidity (sensor as class humidity)
• light (sensor as class illuminance)
• ambient temperature (sensor as class temperature)
• frost warning (binary_sensor as class cold)

Supports: Start (triggers 30min of watering) Stop

!Concern, will the irrigation control break this plugin, since this implementation only assumes one outlet?

Add the URL of this GitHub repository as custom repository (Community -> Settings -> Add custom repository). Then search for "Gardena smart devices" in the "Integrations" tab of HACS and install the integration.

Just copy the "gardena" folder to your 'custom_components' folder.

[your home-assistant-path]/config/custom_components

Add these lines in your configuration.yml

gardena:
  username : !secret gardena_user
  password : !secret gardena_password

Of course you need to make sure you have the secrets available. Note: this components is tested on a clean hass.io install and did work. A extra restart of hass may be needed (if you have the error "No module named 'wt'" in your logs).

##TODO

• submit component to home-assistant
  • Validate if all requirements are met
• fetch garden image
• nice lovelace display for a garden / location

• Mower: Sileno smart (the one with a working capacity of 1000m2)

Since I do not own the devices.

• Smart pressure pump
• smart power adapter
• smart battery
• smart irrigation control (is on my wishlist)
