</div>

Can anybody help me change ui-time-scheduler dashboard to be able to pre-select a required device ?

Similar to its enableDevice option that enables/disables the device.  
And similar to the standard dropdown dashboard widget that accepts input number from msg.payload to preselect it.

I am displaying all the values in a table that has a callback click function.

Thanks

I am not sure this is what you mean, but here is an extract of something I have.

You will also need this file:  
(plants.txt)

```auto
{"timers":[{"starttime":1606528500000,"days":[1,1,1,1,1,1,1],"output":"0","endtime":1606529100000},{"starttime":1616723700000,"days":[0,0,1,0,1,0,1],"output":"1","endtime":1616724300000}]}

```

Nodes:  
You will have to edit the path to the file.

```auto
[{"id":"b5a97d4f.84ed58","type":"function","z":"6dd5ca4d.d1958c","name":"build message","func":"var path = global.get(\"event_paths\");\nmsg.filename = path + \"plants.txt\";\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","x":880,"y":4680,"wires":[["82e4dfc5.1ba768"]]},{"id":"82e4dfc5.1ba768","type":"file in","z":"6dd5ca4d.d1958c","name":"Plants","filename":"","format":"utf8","chunk":false,"sendError":false,"encoding":"none","x":850,"y":4730,"wires":[["46e58700.dc6b38"]]},{"id":"46e58700.dc6b38","type":"ui_time_scheduler","z":"6dd5ca4d.d1958c","group":"c0eea23d.14fd5","name":"Plants","refresh":"60","devices":["Daily","Away"],"customPayload":false,"eventMode":false,"outputs":3,"order":11,"width":"6","height":"1","x":1040,"y":4730,"wires":[["39958344.67685c"],["4e17f8ac.78c5c8","8a49b79e.e2e9d"],["4e17f8ac.78c5c8","c133b660.f9987"]]},{"id":"c0eea23d.14fd5","type":"ui_group","name":"Automatic plant watering","tab":"e92ac76d.c24e7","order":12,"disp":true,"width":"6","collapse":false},{"id":"e92ac76d.c24e7","type":"ui_tab","name":"Real_World_Control","icon":"dashboard","order":14,"disabled":false,"hidden":false}]

Oh. Thats not really what i mean. you are selecting different schedule time files for it right ?

I would like to do the selection of the dropdown of ui-time-scheduler (the place where it displays 'Overview') from an outside function.  
Something like msg.select = id sent to it

This is possible on the standard dropdown widget of the ui-dashboard, but i would like it to work on ui-time-scheduler as well..

any ideea how to make this happen ?

In that example, yes. But that is an **example**.

Once, loaded you can change the schedule from the drop down list.  
So rather than select `overview` select `daily` and that is what you will see.

Does that help?  
(Sorry if I am not good just now. I have a few problems at my end just now too)

</div>

yes. I know how to use it. I am just trying to trigger the selection of 'daily' in your case from an external button.  
I have other places that display data about each item, and it would be nice if the time scheduler widget updates all at once.

Nobody can help ?  
thanks

</div>

(Sorry, been busy with other stuff.)

So you want to select (in the example I posted) `daily` from an input to it?

I don't think that is possible.

The `input` to the node is a schedule.  
The `output` is determined on the schedule and what time it is _now_.

You may need to ask the person who made the node.  
Or: this isn't the node for the job you are wanting to do.

Could you elaborate a bit more on what you want to do?

No promises of an answer though. Sorry. 😉

exactly, the node needs a tweak to make this happen.  
I couldnt figure out how to do it yet 😉 i asked him, no reply yet

I am thinking you may do better with a different node.

`cron-plus` may do what you want easier. Not sure. Just _putting it out there_

Um, but.....

Where does that code _go_?

Is it a flow, or code for a `function` node?

you then send the node msg.selectdevice=0 to it to select the first device  
or "overview" to get back to the default summary

Can I use an `inject` node and is that a `0` or `O`?

I tried with  
`[{"id":"01213c2ee34b5b8c","type":"inject","z":"65c9b63cb09879a0","name":"","props":[{"p":"selectdevice","v":"0","vt":"num"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":1440,"y":640,"wires":[["46e58700.dc6b38"]]}] `  
Doesn't work.
