find device id by search pattern

... Ah.  Posted at (nearly)  the same time.

At least our answers were consistent!

Thanks guys!

So for the room "name" I can declare some global variable for them?

[akbooer]

I check the link from rigpapa and can't find anything about that...

The definitive link for Lua syntax in general, and patterns in particular is:

http://www.lua.org/manual/5.1/manual.html#5.4.1

Don't do that.  Create a lookup table directly from luup.rooms:

Code: [Select]

local room_no = {}

for i,n in pairs (luup.rooms) do
    room_no[n] = i
end
 
print (pretty(room_no))

gives, for one of my machines:

Code: [Select]

{
["MiOS-35104005"] = 2,
["MiOS-35104860"] = 4,
["MiOS-45101161"] = 3,
["MiOS-88800156"] = 8,
["Vera Room A"] = 6,
["Vera Room B"] = 7,
testing = 5
}

But, this could be included in the search.  The problem with names is that there is no guarantee that they are unique, whereas room numbers definitely are.

[DesT]

this is my output....

Code: [Select]

{
Basement = 13,
["Basement - Bathroom"] = 9,
Bathroom = 23,
["Bedroom - Antoine"] = 6,
["Bedroom - Master"] = 20,
["Bedroom - Mathieu"] = 5,
["Bedroom - Twins"] = 4,
["Dining Room"] = 19,
Downstairs = 30,
Garage = 25,
Hallway = 7,
Home = 2,
["IoT Network"] = 27,
["IoT Presence"] = 28,
["IoT SmartSwitch"] = 29,
Kitchen = 21,
["Living Room"] = 10,
["MiOS-50005737"] = 1,
["Office - Nath"] = 18,
["Office - Sebastien"] = 16,
Outside = 26,
["Outside - Basement"] = 15,
["Outside - Front"] = 12,
["Outside - Garage"] = 14,
["Outside - Patio"] = 11,
["Outside - Shed"] = 24,
Upstairs = 17,
["Upstairs - Bathroom"] = 8,
openLuup = 22
}
So it can be a pain 'cause a bunch of rooms start with the same thing...

[akbooer]

...so what's the problem?  I don't quite understand.

[DesT]

That I will need to make my search pattern very precise.  For example, just the word Basement, can give me 3 rooms and Outside can give me 6 results.

Well, if you're just doing a simple search, then, yes.  I thought you would be using the exact name?  This is, perhaps, what @rigpapa meant by "a whole new can of worms".

Searches can also be made to look for "ends with ..." or such like, too.

[DesT]

I think I will stick with the room number

thanks a lot rigpapa and AK for this help this morning.

[DesT]

rigpapa, AK,

Possible to convert the room parameter into an array to be able to pass more than one room and act like a OR

[akbooer]

Code: [Select]

function matchDev ( pattern , rooms)
    local wanted = {}
    for _, r in ipairs ((type(rooms) == "table") and rooms or {rooms}) do wanted[r] = r end
    return function(_, last)
        while true do
            local d
            last,d = next( luup.devices, last )
            if not last or (d.description:match( pattern ) and (not rooms or wanted[d.room_num])) then
                return last,d
            end
        end
    end
end

with this you can write things like...

Code: [Select]

for n,d in matchDev "^D-" do ... end

for n,d in matchDev ("^D-", 3) do ... end

for n,d in matchDev ("^D-", {1,3,5}) do ... end

...now go and learn Lua properly so you can do it yourself!   

[DesT]

Thanks AK

It's in my todo list of 2019... learn Python from 0% and dig a little more into LUA!

[DesT]

AK,

Do you think it's possible that a FOR loop is running too fast for openLuup and that some "command" can be ignored ?

I'm using a FOR loop to "reset" all my smartswitch devices (from the smartswitch plugin) and having some device that are not also reset correctly and it's not always the "same".

Should I add a "wait/sleep" in the loop ?

[akbooer]

Would need a bit more info on that like the actual code plus some logs.
