Domoticz

hello, sorry if the writing is not good but I use a translator.
I am discovering domoticz but there, I am a little lost.
- I installed domoticz on a PI3 then a z-wave key and 2 of the sensors (out of 3) to test. then I used this tutorial (https://www.youtube.com/watch?v=4QNG8lL ... u3&index=7)
- I managed to send a message by email when I activated the sensors.
- I do the necessary to install the 3rd sensor but I had a lot of difficulties. domoticz seems to crash. I unplug and replug the PI3 and I reaccess domoticz. there I discover a bunch of extra lines when I go to device. it is not coherent. I still try to create an alarm (send email) with the 3rd sensor, it does not appear in the list of event device switches. In the meantime I had to restart the PI3 several times because I no longer had access to domoticz.
- being lost, I delete the different sensors/switches as well as the events but not the z-wave key.

- I start again, this time I reinstall the 3 switches by doing "include a node". I rename them to get my bearings and I activate them, the green dot turns blue. - I check in switch, there are 3 times 2 inter - I want to create an event and there I only see the first switch that I installed. - I do + to create an event and in switch there is "nodevice found".
- then the 3 switches appear in event after having done things but I do not know what. but only the office inter is in switch.

can you advise me. i don't know what to do. thanks for the help

If you are new to Domoticz please stop now with the old OpenZwave integration and start with zwave-JS-Ui over MQTT. The OpenZwave project has stopped and will be removed from Domoticz soon.

See the wiki how to install and use zwave-JS-Ui https://wiki.domoticz.com/Zwave-JS-UI

hello everyone and thanks @waltervl for the comment. I gave up on installing domoticz on a synology nas because I had to switch to zwave-JS-UI but it's way too complicated for me. I thought that on a Raspberry PI3 it would be easier and it is but I have this problem. moreover I want a very simple installation, there will only be these 3 switches and nothing else because I'm moving in 2 years and I won't need domoticz where I'm going to live.
it doesn't make sense that I can use 1 switch in the events and the other 2 don't appear. it must be a very small thing to fix but I can't find it.
thanks for the advice

I do not have Zwave but you could read through this wiki page and see if something with your nodes pop up. https://wiki.domoticz.com/Zwave
I have no clue why you see only 3 domoticz devices in the event editor I have never seen this before.
I assume you are using the default domoticz admin account to login domoticz and did not create a new account?
