How to do 'like' comparator in LUA?

[dw89 8]

Hi All,

 

Simple question for those that know:

 

What's the most db efficient way to loop through ALL devices on an HC2 to pull out info on 'any' type of motion sensor that can be bought for an HC2? I only have two different types personally i.e Aeon (where type == 'com.fibaro.motionSensor') and Fibaro (where type == 'com.fibaro.FGMS001'). What other types are out there for other makes? 

 

I want to do a bulletproof loop which will include 'any' Motion Sensor....what's the best way to do this without implicitly knowing the 'type' of each sensor? In my own code I simply implicitly look for those types but, where I to be making it for a disparate system (where I don't know what they have) what's the best way?Ideas much appreciated.

 

KR, Dave:)

 

PS As per title; if you know what a type is I would put == to but, if you know it 'contains' a word like 'motion' how can one code for, what I know as (in other languages) a 'like' comparator. e.g. loop where I find all motion sensors where type LIKE '%motion%'; i.e I don't care what's before it or after it as long as it has 'motion' in the type value.

s:find(pattern [, index [, plain]])

Find the first occurrence of the pattern in the string passed. If an instance of the pattern is found a pair of values representing the start and end of the string is returned. If the pattern cannot be found nil is returned.

just check if pairs are not null
