How to handle timeouts?

[Ittiz]

Does anyone have a good method for figuring out if a z-wave switch actually operated as it's supposed to? I have a door lock that I wrote a LUA script for to lock the door at a particular time every night. However sometimes when the z-wave controller sends the switch command the door lock never gets the message. It wouldn't be a big deal but Domoticz thinks the door is locked anyway. So I can't easily put a check in my script for it. Anyone have any ideas on how I might find out if the lock didn't lock even when Domoticz thinks it did? On a side note there is a z-wave timeout for the node after the switch command is sent. So the z-wave controller knows the message didn't through, it's just Domoticz that doesn't seem to.

Does a refresh in ozwcp reflect the correct status?

OZWCP shows everything correctly. It just seems to be Domoticz that gets a bit lost. So I made a work around in my script to poll the OZWCP. I've got the code below, it works for Kiwkset locks. It also needs a door sensor. Lua code below:

Code: Select all

commandArray = {}
local zwHWID = 2 --CHANGE: The Z-wave node ID for the lock.
local zwnodeID = 14 --CHANGE: The IDX of the Z-wave controller the lock is associated with.
local DoorName = "Porch Door" -- CHANGE: Name of doorlock switch
local DoorSensor = "Office/Porch Door" -- CHANGE: Name of door sensor.
local DoorTimer = "Office/Porch Autolock Timer" -- CHANGE: Name of autolock timer dummy switch

if (otherdevices[DoorTimer] == "On") then
	local s1 = otherdevices_lastupdate[DoorSensor]
	local s2 = otherdevices_lastupdate[DoorTimer]

	local year1 = string.sub(s1, 1, 4)
	local month1 = string.sub(s1, 6, 7)
	local day1 = string.sub(s1, 9, 10)
	local hour1 = string.sub(s1, 12, 13)
	local minutes1 = string.sub(s1, 15, 16)
	local seconds1 = string.sub(s1, 18, 19)
	
	local year2 = string.sub(s2, 1, 4)
	local month2 = string.sub(s2, 6, 7)
	local day2 = string.sub(s2, 9, 10)
	local hour2 = string.sub(s2, 12, 13)
	local minutes2 = string.sub(s2, 15, 16)
	local seconds2 = string.sub(s2, 18, 19)
	
	local t1 = os.time()
	local t2 = os.time{year=year1, month=month1, day=day1, hour=hour1, min=minutes1, sec=seconds1}
	local t3 = os.time{year=year2, month=month2, day=day2, hour=hour2, min=minutes2, sec=seconds2}
	
	local difference1 = t1-t2
	local difference2 = t1-t3
	
	if (difference1 > 60) then
		-- Load data from ZWCFG we can't get anywhere else, get curl from: https://curl.haxx.se/download.html
		local zwcfg = assert(io.popen('curl http://127.0.0.1/zwavegetconfig.php?idx=' .. zwHWID .. ' -la','r'))
		local thedata = zwcfg:read('*all')
		zwcfg:close()
		--done getting zwcfg
		
		-- ver<3.7153 domoticz_applyXPath doesn't work for regular LUA so we get values the hard way.
		--local xmlchunk = string.sub(thedata, string.find(thedata, '<Node id="' .. zwnodeID .. '"'), string.len(thedata))
		--xmlchunk = string.sub(xmlchunk, string.find(xmlchunk, '<CommandClass id="113" name="COMMAND_CLASS_ALARM"'), string.find(xmlchunk, '<CommandClass id="114"'))
		--local alarmtype = string.sub(xmlchunk, string.find(xmlchunk, 'Alarm Type" units="" read_only="true" write_only="false" verify_changes="false" poll_intensity="0" min="0" max="255" value="'), string.find(xmlchunk, 'Value type="byte" genre="user" instance="1" index="1" label="Alarm Level"'))
		--alarmtype = string.sub(alarmtype,125,string.find(alarmtype, '" />')-1)
		--Done getting values ver<3.7153
		
		-- ver>=3.7153 domoticz_applyXPath works.
		local alarmtype = domoticz_applyXPath(thedata,'//Driver/Node[@id="' .. zwnodeID .. '"]/CommandClasses/CommandClass[@name="COMMAND_CLASS_ALARM"]/Value[@label="Alarm Type"]/@value')
		--Done getting values ver>=3.7153
		
		alarmtype = tonumber(alarmtype)--these need to be numbers because of LUA.
	
		--if (otherdevices[DoorSensor] == 'Closed' and otherdevices[DoorName] == 'Unlocked') then --should work but doesn't always
		if (otherdevices[DoorSensor] == 'Closed' and alarmtype ~= 24) then 		         	--so we check OZW instead.
			commandArray[DoorName]='On' --if the door is unlocked too long lock it
		end
	elseif (otherdevices[DoorSensor] == 'Closed' and difference2 < 60) then
		commandArray[DoorName]='On' --if the user just clicked the autolock button lock right away
	end 
end
return commandArray
