This is what i made so far from the examples.
(i also speak better russian than lua) :lol:

Code: Select all

x = tonumber(uservariables['Tag_Green'])

commandArray = {}
 if ( uservariables["Tag_Green"] ~= "AWAY" ) and (otherdevices["TAG"]=='Off') then
	print('<b style="color:#0099FF">Tag_Green AANWEZIG RSSI:'..x .. ' dBm</b>')
    commandArray['TAG']='On'
 elseif ( uservariables["Tag_Green"] == "AWAY" ) and (otherdevices["TAG"]=='On') then
  	print('<b style="color:Red">Tag_Green AFWEZIG</b>')   
    commandArray['TAG']='Off'
 elseif ( uservariables["Tag_Green"] ~= "AWAY" ) then 
	 print('<b style="color:#0099FF">Tag_Green AANWEZIG RSSI:'..x .. ' dBm</b>')
	 commandArray['UpdateDevice']='2606|0|'..tostring(uservariables['Tag_Green'])
end
if ( uservariables["Tag_Green"] ~= "AWAY" ) and  tonumber(x) <= -68 and tonumber(x) >= -76 then	 
	 print('<b style="color:#0099FF">Tag_Green EETKAMER RSSI:'..x .. ' dBm</b>')
end
if ( uservariables["Tag_Green"] ~= "AWAY" ) and  tonumber(x) <= -77 and tonumber(x) >= -87 then	 
	 print('<b style="color:#0099FF">Tag_Green WOONKAMER RSSI:'..x .. ' dBm</b>')
end
return commandArray

What is the result in the log when you use this code? It will show the current processed info:

Code: Select all

commandArray = {}
for variableName, variableValue in pairs(uservariablechanged) do
	print("variableName:", variableName, "   variableValue:", variableValue)
	if (variableName == 'Zhenya_SitRm') then
		if tonumber(variableValue) <= -51 and tonumber(variableValue) >= -71 then
			commandArray['ZSitRoomBT'] = "On"
		end
	end
	if (variableName == 'Zhenya_SitRm') then
		if variableValue == "AWAY" then
			commandArray['ZSitRoomBT'] = "Off"
		end
	end
end
return commandArray
ps. what is the name of the script you use?

Thanks

I understand that you have an uservariable that is updated by the script.
The you have a switch, TAG, that is updated within this script.

What is doing this?

Code: Select all

    commandArray['UpdateDevice']='2606|0|'..tostring(uservariables['Tag_Green'])
Is it an uservariable event driven or device driven?

I put the RSSI value in a virtual custom sensor (idx2606) for graph.

I don't see the LUA error out there, so what is shown when that is happening?

Sorry Jos,

It triggers a fault when the variable switches to "AWAY"

Code: Select all

2016-05-16 21:01:05.868 Error: EventSystem: in script_variable_bt2.lua: [string "--script_variable_bt2.lua..."]:6: attempt to compare nil with number
Would this be when the script attempts "tonumber" when the variable string is "AWAY"?

Perhaps when the beacon is away, the reported value is NIL?

Maybe something like this works:

Code: Select all

commandArray = {}
for variableName, variableValue in pairs(uservariablechanged) do
	numVal = tonumber(variableValue)
	--
	if numVal == nil then numVal = 0 end
	if (variableName == 'Zhenya_SitRm') then
		if variableValue == "AWAY" then
			commandArray['ZSitRoomBT'] = "Off"
		elseif numVal <= -51 and numVal >= -71 then
			commandArray['ZSitRoomBT'] = "On"
		end
	end
end
return commandArray

Our language probably sounds as foreign to Sean as Russian anyways ;)

No, you're right. It was just something that came up to my mind.

:D

This is why when English people hear something garbled and unintelligible, we describe it as sounding like "Double Dutch". :lol:

Bizarrely, the Dutch language is The English Language's closest relative... go figure :roll:

I'm still getting issues on reboot

The status is active(exited) after reboot

the log says:

Code: Select all

2016-05-17 17:58:23,835 - root - CRITICAL - Error : hci0 interface not Running. Do you have a BLE device connected to hci0 ? Check with hciconfig !

I have 3 Nut and all visible with a BLE scanner

Any idea what I should do or check?

Hmmm. This is odd. I left my Nut Tag at the same place this whole night and day.

Looking at the RSSI graph of this Tag it shows a clear difference when someone is at home or all left (for work)
When no one is at home the signal is quite stable according to the graph.

When i want to use it for indoor positioning system it would be better when the signal is stable as well when someone is at home.
Maybe it is some device that interferes the bluetooth signal... Have to investigate further.

Is there already somebody with this same experience?

I found placing a bottle of "Dr. Pepper" next to my tag caused a 25 point move. Took me a while to figure it out. :x
Stranger still, cups of tea or coffee had not affected it before :? ....... Maybe I'll stick with tea :lol:
