Pushnotification when dishwasher/washing machine is ready?

Hard to say anything just based on this info. I suggest adding more debug lines ( = print more stuff to log) on the script to see where it goes wrong. With just a quick look I noticed something that might play a role:

Code: Select all

local energy_consumption      = 'verbruik wasmachine'         --Name of Z-Wave plug that contains actual consumption of washingmachine (in 
-- sWatt, sTotalkWh              = otherdevices_svalues['Clothes Washer Power Usage']:match("([^;]+);([^;]+)")
-- washer_usage                  = tonumber(sWatt)
washer_usage                  = tonumber(otherdevices_svalues[energy_consumption])

Is your device "verbruik wasmachine" such it only reports Watts? If it reports energy (W & kWh) then you need the split which you have now commented out (and use correct device name there.

Considering the various operating modes of the targeted devices that I own, I doubt that measuring power consumption and issuing an alarm/notification after X seconds of ample usage is very reliable. And of course this requires acquiring hardware that can measure the power usage of such devices and this will need to be quality hardware as the targeted devices will typically have a peak power rating (far) above 2000 Watts. Which doesn't seem like a very good investment as I can already deduce the power usage of these devices from my P1 reports. I'd guess it would be far cheaper and exact to get yourself a light monitoring device to detect whether the control light on the dishwasher/washing machine is on. Or to stay with the subject: signal when it turns off.

You're free to do it however you like.
I use a Tp-link hs110, rated for 3500w, and the script works flawlesly for my washing machine.

With P1 you will only know the total power usage, so that won't work.

this is my device:


and this is the editted script:

Yesterday the Watt's were like 0, but the script said

so it went to step 2 and there it gets looped.

So based on your screenshot the device shows both W and kWh so you need to change these lines:

Code: Select all

-- sWatt, sTotalkWh              = otherdevices_svalues['wasmachine']:match("([^;]+);([^;]+)")
-- washer_usage                  = tonumber(sWatt)
washer_usage                     = tonumber(otherdevices_svalues[energy_consumption])

to

Code: Select all

sWatt, sTotalkWh              = otherdevices_svalues['wasmachine']:match("([^;]+);([^;]+)")
washer_usage                  = tonumber(sWatt)

That is, uncomment first two and remove third. If it does not work, please try to add more debug lines as suggested. Start with something as simple as:

Code: Select all

sWatt, sTotalkWh              = otherdevices_svalues['wasmachine']:match("([^;]+);([^;]+)")
washer_usage                  = tonumber(sWatt)
print('Current washer usage is '..washer_usage..'W')

it look liked i had 2 devices names "wasmachine" 1 the switch and 1 the power usage.

now i get this output

Code: Select all

2017-06-15 14:31:00.459 LUA: 50

Tonight i will test if the script works

Thanks so far!

[Nautilus]

Yes, two devices with the same name will lead to trouble in this kinds of situations

In any case, seems the script now reads correctly the current usage (0W) so I think you have good changes to get it working this evening!

[maomanna]

cause the powerusage was below the minimum, the timer counted.
When the counter ended, i recieved a notification over telegram!

thanks for your help!

[Nautilus]

Great!

Hi guys, i tried the script as posted here in this topic

return commandArray

I have added the two uservars (“washingmachine_status” and “washingmachine_counter”) , as a integer and with the value 0.
I also changed the name of the “wasmachine” to “WattWasmachine” because the watt counter has this name in my system.

But I get the error below.

What is going wrong?

[jvdz]

Looks like the device WattWasmachine doesn't contain the right values. What is the exact content shown in the devices tab for it?
EDIT: This statement expect the svalue to contain "Current usage;Total kWh usage":

Code: Select all

sWatt, sTotalkWh              = otherdevices_svalues['WattWasmachine']:match("([^;]+);([^;]+)")

Likely your device only has the current usage?
If so just modify the script to:

Code: Select all

--sWatt, sTotalkWh              = otherdevices_svalues['WattWasmachine']:match("([^;]+);([^;]+)")
--washer_usage                  = tonumber(sWatt)
washer_usage                  = tonumber(otherdevices_svalues['WattWasmachine'])

I wilbtry this tomorrow. I think you are right. The wattwasmachine is only current usage. No total count. I am using the coolcam neo powerplugs.
Hope this will work

[Goldwing1973]

I've had the same idea a little while ago, and this is how i solved it.
I'm using a Fibaro Wall Plug to measure its power consumption, when it uses 300watt or more a variable sets to on and writes it to the log.
Next it's waiting until the power consumption becomes 1.3 watt (ready, but the display on the washing machine still lid, 15 minutes later the display will turn off and power consumption will be 1 watt)
Then send a message, and turn on the most left light above the dining table.

Works like a charm and has a huge WAF (Wife Acceptance Factor)

If the script doesn't work for me I can always try your Blocky. Blocky is more my language then LUA

This did the trick it works now.
Now only to tweek it to the right value's
