Kitty Litter Tracking Sensor

[ben53252642]

I bought the ScoopFree Ultra kitty litter and added a Z-Wave magnetic door sensor at the end part to sense when the "storage section" opens and closes.

Each time the cat uses the kitty litter it updates a counter in Domoticz so I can tell when the kitty litter needs changing (after x cycles):

The device name for the magnetic door sensor is: Kitty Litter

The device name for the counter sensor is: Kitty Litter Cycles

You may need to change the "Closed" to "Open" depending on your setup, it's a pretty simple script.

Code: Select all

commandArray = {}
time = os.date("*t")
counter = otherdevices_svalues['Kitty Litter Cycles']
counter = tonumber(counter)

t1 = os.time()
s1 = otherdevices_lastupdate['Kitty Litter Cycles']
year1 = string.sub(s1, 1, 4)
month1 = string.sub(s1, 6, 7)
day1 = string.sub(s1, 9, 10)
hour1 = string.sub(s1, 12, 13)
minutes1 = string.sub(s1, 15, 16)
seconds1 = string.sub(s1, 18, 19)
t2 = os.time{year=year1, month=month1, day=day1, hour=hour1, min=minutes1, sec=seconds1}
cycletime = (os.difftime (t1, t2))

if (devicechanged["Kitty Litter"] == 'Closed' and cycletime > 240) then
counter = counter + 1
commandArray['UpdateDevice'] = otherdevices_idx['Kitty Litter Cycles'] .. '|0|' .. tonumber(counter)
end

return commandArray

Poop tracker, I love it

Ha great, i was looking for this. What type of sensir did you create for the cycles?

It's just a counter, also fyi they sell re-usable trays for the ScoopFree on Amazon.

this is pure brilliance!

Hello Ben,
i use your simple script, with a virtual switch (to try) and change the names from the sensor and counter in the Script (not more).
But it doesn't work.

In the Stratus Protocoll is this error:
Error: EventSystem: in brennerstarts: [string "commandArray = {}..."]:17: attempt to index global 'devicechanged' (a nil value)

What is wrong?
Thx Bernoo

You probably have the Lua script set to type "ALL" instead of "Device". Look on the events page.

Hello Ben,
yes, that was wrong, and the error message is gone. But he still does not count. There must be another mistake.
I do not understand that.

Thx for your fast help.

If your using a virtual switch for testing, that would only have "On / Off" states.

This line needs to be changed:

if (devicechanged["Kitty Litter"] == 'Closed' and cycletime > 240) then

To:

if (devicechanged["Kitty Litter"] == 'Off') then

I removed the cycle time, basically each time you turn off the test switch it should now + the counter. This is only so you can see it working with the test script, the original script above should work fine with an actual door / contact sensor.

Ben,
that was it, it works!!! Thank you,
thank you for your help.

I change it after install the Hardware Switch next Week

Nice !
Would be nice if there was a reset-button (virtual on the screen) which could be pressed after cleaning the cat-litter.
How can we do that ?
I have made some hardware for the Cat Robot Litter, will post that as soon it's ready (now in prototype fase, works nice already).

I am trying to make a reset button and a counter.

What I want to do is this:
1) a counter which counts every cat litter cycle, that works now.
2) a total counter which counts the total cycles
3) a reset button which reset the counter (1) to 0.

I have made a uservariable:

'KattenbakCyclusTeller Integer'

And I use the script below.

If I add the line 'uservariables['Kattenbakcyclusteller'] = otherdevices_idx['Kattenbakcycles'] ' the script doesn't work anymore.

I hope somebody can help a little ?

Regards,

Arthur

Did you manage to get this working?

[askmurphy]

It works !

Look at this:

Kattenbak-code:

Code: Select all

-- You probably have the Lua script set to type "ALL" instead of "Device". Look on the events page.
commandArray = {}

time = os.date("*t")
counter = otherdevices_svalues['Kattenbakcycles']
counter = tonumber(counter)

totalcounter = otherdevices_svalues['Kattenbakcycle-totaalteller']
totalcounter = tonumber(totalcounter)

t1 = os.time()
s1 = otherdevices_lastupdate['Kattenbakcycles']
year1 = string.sub(s1, 1, 4)
month1 = string.sub(s1, 6, 7)
day1 = string.sub(s1, 9, 10)
hour1 = string.sub(s1, 12, 13)
minutes1 = string.sub(s1, 15, 16)
seconds1 = string.sub(s1, 18, 19)
t2 = os.time{year=year1, month=month1, day=day1, hour=hour1, min=minutes1, sec=seconds1}
cycletime = (os.difftime (t1, t2))

if (devicechanged["Kattenbaksensor"] == 'On' and cycletime > 60) then
counter = counter + 1
totalvalue = totalcounter + 1

    table.insert (commandArray, { ['UpdateDevice'] = otherdevices_idx['Kattenbakcycles'] .. '|0|' .. tonumber(counter) } )
    table.insert (commandArray, { ['UpdateDevice'] = otherdevices_idx['Kattenbakcycle-totaalteller'] .. '|0|' .. tonumber(totalvalue) } )

end

return commandArray

Kattenbak-reset code:

Code: Select all

-- You probably have the Lua script set to type "ALL" instead of "Device". Look on the events page.
commandArray = {}

if (devicechanged["Reset kattenbak teller"] == 'Group On') then
       table.insert (commandArray, { ['UpdateDevice'] = otherdevices_idx['Kattenbakcycles'] .. '|0|' .. tonumber(0) } )
      --  table.insert (commandArray, { ['UpdateDevice'] = otherdevices_idx['Kattenbakcycle-totaalteller'] .. '|0|' .. tonumber(0) } )
--   commandArray['UpdateDevice'] = otherdevices_idx['Kattenbakcycles'] .. '|0|' .. tonumber(9)
  -- commandArray['UpdateDevice'] = otherdevices_idx['Kattenbakcycle-totaalteller'] .. '|0|' .. tonumber(9)
end

return commandArray
