RobbSmarrt Rotary dimmer Z-Wave 2-wire

Installation with the Home Assistant:

The last smart home controller where we will add the dimmer is Hass. We use an Aeotec Usb Z-Wave stick to add it. The first step is to remove the old switch / dimmer. Make sure you have turned off the power. A schematic for a 2 wire and 3 wire connection is included (with and without blue wire). It can be experienced to go for the 3-wire variant. If you have connected everything correctly, please wait a while before switching the power back on.

First log in to Hass via your browser and go to your configuration and then to Z-Wave. Then click on "add node secure" to start adding. Then supply the dimmer with power. HASS gives a very short notification that the addition has started.

Normally you have to press a small pin in the reset hole (3x in quick succession) but with me it was found immediately. While adding, the dimmer LED will light red and then flash to indicate that it is learning. And that a calibration is carried out. Make sure there is a lamp in the luminaire, because it calibrates with the correct lamp.

When configuring the dimmer I see all the settings and the correct nodes. It is striking that everything is added 2x. This is not a problem because you can simply delete the incorrect nodes. It is complete, see a dimmer, on/off switch, total consumption and current consumption. And more importantly it responds well to my commands.

You get the total consumption, current consumption, power, voltage.

I would like the dimmer to be switched on after sunset. I use the bigtimer as a trigger for this and switch on the dimmer..

HASS conclusion:

This dimmer also works perfectly with this smart home system. Only thing I noticed is that it was added 2x.
