Get Domoticz Uptime in Lua or via Json?

[ben53252642]

Is it possible to get Domoticz uptime using Lua or via the Json interface?

I'm wanting to create a Lua script with an if condition that Domoticz must have been up for 10 minutes before it will run.

Solved by guessing!

Code: Select all

/json.htm?type=command&param=getuptime

Code: Select all

{
   "days" : 1,
   "hours" : 7,
   "minutes" : 36,
   "seconds" : 45,
   "status" : "OK",
   "title" : "GetUptime"
}

Example Lua Script to get Domoticz uptime in minutes.

In the below example, in additional to the Motion Sensor changing to "On", Domoticz uptime must be over 10 minutes.

Code: Select all

-- Domoticz Configuration
username="USERNAME"
password="PASSWORD"
server="192.168.0.5"

commandArray = {}

-- Get Domoticz Uptime in Minutes
json = (loadfile "/root/domoticz/scripts/lua/JSON.lua")()
command='curl -s -k "https://'..username..':'..password..'@'..server..'/json.htm?type=command&param=getuptime"'
local handle = io.popen(command)
local result = handle:read("*a")
handle:close()
output = json:decode(result)
domoticzuptime = ((output.days * 1440) + (output.hours * 60) + (output.minutes))

if (devicechanged["Motion Sensor"] == 'On' and domoticzuptime > 10) then
commandArray['Main Bedroom'] = 'On'
end

return commandArray

in dzVents you can get the required info by

Code: Select all

domoticz.startTime.minutesAgo

I like the idea of having a button that shows how long Domoticz is up so I can use it in Dashticz.
I did find after trial and error some code that works...

Code: Select all

-- Domoticz Configuration
server="192.168.2.14"
port="8081"
switch="Uptime"

json = (loadfile "/home/pi/domoticz/scripts/lua/JSON.lua")()
local config=assert(io.popen('curl "http://'..server..':'..port..'/json.htm?type=command&param=getuptime"'))

local uptime = config:read('*all')
config:close()
local jsonGetUptime = json:decode(uptime)

days = jsonGetUptime.days
hours = jsonGetUptime.hours
minutes = jsonGetUptime.minutes
dzuptime = days.. " dagen " ..hours.. " uur " ..minutes.. " minuten"

commandArray = {}

  print('(Uptime) '.. dzuptime)
  table.insert(commandArray, { ['UpdateDevice'] = otherdevices_idx[switch] .. '|0|' .. dzuptime })

return commandArray

Because I'm no programmer there can be a better solution. Be so kind to let me know.

a dzVents solution

Code: Select all

return { 
    on = {   timer  =   {"every minute"}},  
                
    execute = function(dz)
        local uptimeTextDevice = dz.devices("Domoticz uptime")
        
        local minutes = dz.startTime.minutesAgo%60
        local days    = dz.startTime.daysAgo
        local hours   = dz.startTime.hoursAgo%24
        
        uptimeTextDevice.updateText(days .. " dagen, " .. hours .. " uur en " .. minutes .. " minuten"  )
    end
}

@waaren: Thanks!

Hello, I've been messing around with the script above, but can't really figure it out, maybe someone who has an idea what else I need to change.

What I want is 1 text device where all 3 my domoticz servers can be seen. I imagine the layout as follows.

Domoticz uptime (device name)
Master 2 days 2 hours 22 minutes (result)
Slave 1 2 days 2 hours 22 minutes (result)
Slave 2 2 days 2 hours 22 minutes (result)

Code: Select all

-- Domoticz Configuration
server1="192.168.1.100"
port1="8080"
server2="192.168.1.101"
port2="8080"
server3="192.168.1.102"
port3="8080"
switch="Domoticz uptime"

json = (loadfile "/home/pi/domoticz/scripts/lua/JSON.lua")()
local config=assert(io.popen('curl "http://'..server1..':'..port1..'/json.htm?type=command&param=getuptime"'))
local config=assert(io.popen('curl "http://'..server2..':'..port2..'/json.htm?type=command&param=getuptime"'))
local config=assert(io.popen('curl "http://'..server3..':'..port3..'/json.htm?type=command&param=getuptime"'))

local uptime = config:read('*all')
config:close()
local jsonGetUptime = json:decode(uptime)

days = jsonGetUptime.days
hours = jsonGetUptime.hours
minutes = jsonGetUptime.minutes
dzuptime = days.. " dagen " ..hours.. " uur " ..minutes.. " minuten"

commandArray = {}
 local m = os.date('%M')
 if (m % 5 == 0) then --Intervaltijd
  print('(Uptime) '.. dzuptime)
  print('(Uptime) '.. dzuptime)
  print('(Uptime) '.. dzuptime)
  table.insert(commandArray, { ['UpdateDevice'] = otherdevices_idx[switch] .. '|0|' .. dzuptime })
 end
return commandArray

If you want to stick to classic Lua it could look like something as below.
Will probably fail if one of the systems or domoticz service is down.

Code: Select all

-- Domoticz Configuration

local uptimeString = ''
local uptimeSensor = 'Uptime'
local systems = 
        { 
            { 'master','192.168.1.100', '8080' },
            { 'slave1','192.168.1.101', '8080' },
            { 'slave2','192.168.1.102', '8080' },
        }    
            
local json = (loadfile 'scripts/lua/JSON.lua')()

for _, system in ipairs(systems) do
    local curl = "curl 'http://" .. system[2] .. ":"  .. system[3] .."/json.htm?type=command&param=getuptime'"
    -- print(curl)
    
    local config=assert(io.popen(curl))
    local uptime = config:read('*all')
    config:close()
    local jsonGetUptime = json:decode(uptime)

    days = jsonGetUptime.days
    hours = jsonGetUptime.hours
    minutes = jsonGetUptime.minutes
    uptimeString = uptimeString .. system[1] .. ' uptime: '  .. days.. ' dagen ' ..hours.. ' uur ' ..minutes.. ' minuten' .. '\n' 
end

uptimeString = uptimeString:sub(1, -2) -- remove trailing \n
-- print('(Uptime) '.. uptimeString)

commandArray = { ['UpdateDevice'] = otherdevices_idx[uptimeSensor] .. '|0|' .. uptimeString } 
return commandArray

Who, that's fast, thank you very much for that.
This is basically for what I was looking for.
But you ask if I want to hold on to Lua, no not necessarily.
I found this and it worked for me.

If you say there is a better solution, yes please let me know.

The potential issue with an approach like this with curl, is that if you don't get a reply because a system is down or domoticz is not responding that other scripts are no longer executed. Because the domoticz event system is single threaded such a situation will block all other event scripts.

dzVents offers multiple alternatives for this.

- To get the information from multiple systems as is needed to solve your request, you could have the systems all send there uptime based on the dzVents script I posted in this thread earlier via an openURL command (which is async and therefore cannot block the event system) to the central system. They would have the choice to send it to a domoticz uservar or to trigger a customEvent. In both cases a dzVents script on the central system would be triggered to collect the information and present it in the virtual text Sensor.
- Another way would be to update a textSensor on all systems and have dzVents on the master system to collect the data from these sensors; again via an async openURL command.

These dzVents based alternatives would require a bit more coding but with the advantage of added resilience against outages or other unforeseen problems.

btw. dzVents scripts are 100% Lua

Okay, I initially tried your script on the slave and then wanted to make it visible with shared devices on the master but that didn't work, it didn't show up on the master.
Then I saw this script.
Anyway I am not a programmer and so I have to rely on google, ctrl-c and ctrl-v
So I really don't know how to do this and I don't want to bother people with that.
