Easiest way to control multiple switches from one switch Topic is solved

[Domoberry]

Hi Forum,
Typical use case this season: got a few smart plugs controlling some xmas lights and I want the timer in a one of the switches to control them all.
What is the most simple and/or practical way to achieve this?

Initially, I assumed 'slave/sub devices' would be the way to go, but as the Wiki already suggests ("one of the most difficult chapters" ) I cannot get my head around it for this purpose.
A Dzvents script triggered by a switch and sync the others accordingly seems straightforward.
Or, using a series of json commands with 'on action' / 'off action' to propagate from one switch to the other
or?

probably quite simple...

Make a scene, include all the devices you want to control and set the timer(s). That's all. Can be done in a few minutes. I do this with roller shutters and you can do it with smart plugs as well.

So this is not a sync of a "leading" smart plug. But you can interpret this scene as the (virtual) master plug

Hi Imautohuttraeger,

Thanks for the tip, just what I need and simple!!

My first group...

I did however opt for 'Group' rather than 'Scene' as a Group more closely resembles what I was looking for.

Did you succeed?
I'm trying to set-up a scene for Melcloud (Mitsubishi air conditioner) that is controlled with a set of switches (mode level switch for off/warm/cold/vent..., temp that is also a level switch, one level for each temperature and many other switches).
I just would like to make a scene or group that sets mode to warm and temperature to 20° but it does not look reliable, although manipulating the individual switches works correctly.
Finally I would like to setup a timer for this scene/group.
I'm using stable version 2020.2 and finally wondering about the fact there might be a bug, but it looks surprising to me.

Seems as if your switches are not simple on/off switches. I guess if you want to control selector switches you need to make a script (under menu point "Events") that can handle different states of a particular switch.

Indeed, it looks like!
Weirdly the level is nevertheless implemented in the group définition.
I tried making a simple blocky logical control in place of the group but this idies not works better.
There might be an issue on the python plugin...

Scenes and Groups are perfectly capable of setting a selector switches or dimmer switches to any available level. No need to script fot that purpose.

@Waaren, on multilevel grouped switches, there are fields for both on/off and level. Do you have more piece of information regarding this?
To my opinion, level 0% means off but what does on means?
Best,

Patrice

Scene on
When configured as On + level > 0 -->> switches to the set level (is implicit On).
When configured as Off + any level -->> switches to level 0 and Off
When configured as On + level 0 -->> switches to level 0 and Off

Group On
When configured as level > 0 -->> switches to the set level (is implicit On).
When configured as level 0 --->> switches to level 0 (is implicit Off)

Group Off
When configured as level > 0 -->> switches to level 0 (is implicit Off).
When configured as level 0 --->> switches to level 0 (is implicit Off) // Yes no change but can trigger a subsequent event.

How about using the first switch as the activation device in a scene with the others?

only missing the option to change the scene/group icons

Oh - I haven't known this, thanks. Seems to be quite interesting - I will busy myself with it now.
