Kungergely Did you read the instructions at the Chirp website? To start using Chirp: * Wait until your plant needs to be watered, so you can tell Chirp how much moisture is too little. * Install the battery (watch the polarity!) * Carefully insert the device into the soil up to the line shown on the device. Gently pack the soil around Chirp, so that there are no gaps between the sensor and the soil. * Push the button. Try not to wiggle the device too much while doing that. Do not touch the device, plant or pot for 5 seconds after pushing a button - Chirp needs some time to measure the moisture level undisturbed. * Water the plant. Try not to get too much water on the Chirp.

Kungergely In the way you want to you most probably can't. The roller shutter will take up two out of the 4 switches (see e.g. http ://www.homesystem.sk/uploads/2/8/0/2/28026557/published/kompozycja-280_1.png?1560329684 for an example of the way these roller shutters are wired) so you'd have only 2 switches left for the lights. Thus you'd have to connect two of your lights to a single switch output. Or you should just buy a 3-gang switch for the lights and then a separate 2-gang switch for the roller shutter. That's how these things are usually installed anyway (connected to a dedicated switch that is).
