Script to track usage time per day/week

[felix63]

I have a switch that (Alivechecker) to see whether or not a PS4 is on. Now I want to have a simple way of keeping track of daily and weekly usage. Preferably in such a way that I can trigger some alerts/actions if daily/weekly quota is being exceeded.

As I have a predisposition to laziness I was wondering if someone out there already did something similar?

This script could be a start. Not full tested but the basics works.

Code: Select all

-- track usage.lua
local trackDevice = 'Alivechecker'  -- name of device to be checked

return 
{
    on = {  timer = { 'every 15 minutes', 'at 23:59','at 00:01' }, 
            devices = { trackDevice }},

    logging = { level = domoticz.LOG_INFO, marker = "tracker" },

    data = { tracker = { initial = {} }}, 

    execute = function(dz, item)
        local trackDevice = dz.devices(trackDevice)
        local weekUsage, dayUsage = 0, 0
        local dayLimit = 3600 -- daily limit in seconds
        local weekLimit =  7 * dayLimit -- weekly limit in seconds
        
        local function initPersistent()
            if not(dz.data.tracker.lastState) then 
                dz.data.tracker.lastState = item.state 
                dz.data.tracker.dDate = dz.time.dDate

                dz.data.tracker.days[dz.time.dayAbbrOfWeek] = 0
                dz.log('persistent data initialized; system can now be used', dz.LOG_FORCE )
                return true -- initialized now
