ZOHO: smart rain barrels have been installed

The ZOHO rain barrels have been installed! The rainwater from the roof of the Hofbogen is led to the letters and does not end up in the sewer. The smart system in the letters looks at the weather forecast via the internet. When a heavy shower is approaching, it releases its water into the surrounding garden and creates buffer capacity for the coming rain shower. During long periods of drought, it retains water to provide the surrounding greenery with water.
