Washing Machine State Machine

[Likonaus (Olaf)]

I can´t read the power consumption, voltage etc. from a Sonoff POW flashed with Sonoff-Tasmota. The information page on the device says “Program version 5.0.6”

I have tried a few MQTT lines, such as:

Number nWama_Energy "Energy [%.1f]"  { mqtt="<[mosquitto:tele/sonoff-wama/ENERGY:state:default]" }

Number nWama_Energy "Energy [%.1f]"  { mqtt="<[mosquitto:tele/sonoff-wama/Power:state:default]" }

From the device console I see the following messages

01:10:22 MQTT: tele/sonoff-wama/STATE = {"Time":"2017-07-25T01:10:22", "Uptime":2, "Vcc":3.189, "POWER":"ON", "Wifi":{"AP":1, "SSID":"Home Zone", "RSSI":100, "APMac":"34:31:C4:5F:AC:8A"}}
01:10:22 MQTT: tele/sonoff-wama/ENERGY = {"Time":"2017-07-25T01:10:22", "Total":0.040, "Yesterday":0.015, "Today":0.025, "Period":2, "Power":30, "Factor":0.91, "Voltage":230, "Current":0.143}

I either see a dash or 0.0 as the item value.

Can somebody please give me a hint or share his items configuration?

[Likonaus (Olaf)]

Thank you so much for sharing.
In order for that JSONPATH thing to work, I would need a rule, correct? If yes, would you also share your rule, please?

[Olymp (Sergey M)]

Rule is not necessary, you need to establish a transformation.

[Likonaus (Olaf)]

Bingo, thank you!!!

Also check out: https://github.com/arendst/Sonoff-Tasmota/wiki/openHAB#mandatory-topics--items

@Olymp feel free to add your items to the wiki article (in the right place)

[Likonaus (Olaf)]

When I use the command

grep "Washingmachine_Power changed" /var/log/openhab2/events.log

on a Linux machine the output is only

Binary file /var/log/openhab2/events.log matches

instead of that nice listing . How can I extract the lines "nWama_Current changed " from the log file?

[waitz_sebastian (Sebastian)]

That does not seem to be the active log file but rather a compressed historical logfile.
You could do ‘zcat logfile | grep pattern’.
But if you’re looking for recent events you habe to Check the active logfile.

Short question:

This values

val Number MODE_OFF = 0
val Number MODE_STANDBY = 1
val Number MODE_ACTIVE = 2
val Number MODE_FINISHED = 3

Can i use them inside my sitemap to make some visibility-switches too?

Or can i use this only inside the one rule rules-file, in that this is declared?

[Confectrician (Jerome Luckenbach)]

This values are limited to the rules file if I remember correctly.

But you could of course add a number item and map it to on of the 4 available states within your rules.

[halloween]

I already have this, because without the number item the state machine will not work???

So my number item has 0, 1, 2 , … and inside the rules file i can use the declared strings “mode_off” and so on.

So my sitemap looks like this:

Switch item=Switch_Dummy  visibility=[number_item==0]

But this would be more readable if i can use it like this:

Switch item=Switch_Dummy  visibility=[number_item==MODE_OFF]

But that´s ok, it works well with the numbers, would be only nice to have if i can use the declared names everywhere.

[ThomDietrich]

The variable names, e.g. MODE_OFF can not be used outside the rule. They are defined locally in that file.

However what is possible and I learned to be the better solution for such cases is to use Strings instead of Numbers for the state:

//Item:
String Washingmachine_OpState "Washingmachine State [MAP(opstate.map):%s]"

// In rule:
Washingmachine_OpState.postUpdate("FINISHED")

From a programmers point of view that might be a bit weird but it’s the better option from a openHAB pov.

This is my Solution for my Dryer … The crease protection had driven me crazy

Now it works very fine I became a Notification when the Crease Protection begins

val Number MODE_OFF = 0
val Number MODE_STANDBY = 1
val Number MODE_ACTIVE = 2
val Number MODE_FINISHED = 3
val Number MODE_CREASE_PROTECTION = 4
var Number Trockner_Counter = 0

    rule "Trockner Status"
    when
        Item Steckdose_Trockner_Power changed
    then
      if (Steckdose_Trockner_Power.state < 1) Trockner_Status.postUpdate(MODE_OFF)
      else if (Steckdose_Trockner_Power.state > 100  && Trockner_Status.state !== (MODE_CREASE_PROTECTION) || Steckdose_Trockner_Power.state > 500){
        Trockner_Status.postUpdate(MODE_ACTIVE)
      }
      if (Trockner_Status.state == (MODE_ACTIVE) && Steckdose_Trockner_Power.state < 2){
        Trockner_Counter = Trockner_Counter + 1
      }
      if (Steckdose_Trockner_Power.state > 1 && Steckdose_Trockner_Power.averageSince(now.minusMinutes(2)) < 2) {
        if (Trockner_Status.state == MODE_OFF) Trockner_Status.postUpdate(MODE_STANDBY)
      }
      if (Trockner_Counter > 6){
        if (Trockner_Status.state == MODE_ACTIVE){
          Trockner_Counter = 0
          Trockner_Status.postUpdate(MODE_CREASE_PROTECTION)
        }
      }
      if (Steckdose_Trockner_Power.averageSince(now.minusMinutes(30)) < 150){
        if (Trockner_Status.state == (MODE_CREASE_PROTECTION)) Trockner_Status.postUpdate(MODE_FINISHED)
      }

[kintrupf (Frank Kintrup)]

I’m currently trying to build this myself. I’ve added a Tasmota flashed Sonoff POW to my washing maschine and can successfully communicate with it via MQTT

Right now I’m relying on the telemetry messages from the POW every 10 seconds to sample the power levels. While that works fine I really don’t want to send the telemetry then so often, especially when the washer is off.

I read through most of this thread and also through the Tasmota Wiki about all available MQTT commands and other configuration options, but I could not find anything that would enable the POW to publish MQTT messages whenever the power level changes a certain amount of Watt, say 3 Watts or more. Is this possible?
If not, how did you sample the power levels? Thanks!

[binderth (Thomas Binder)]

simply add a rule, which sends a Sonoff Command to change the interval, I have this one:

Number Sensoren_SonoffHeatingIR_TelePeriod	"IR-Heizung Intervall [%d s]"  	{ mqtt=">[<BROKER>:cmnd/sonoffHeatingIR/TelePeriod:command:*:default],<[<BROKER>:stat/sonoffHeatingIR/RESULT:state:JSONPATH($.TelePeriod):.*TelePeriod.*]" }

This item sends the “TelePeriod” command to the Sonoff and receives the present TelePeriod from the JSON-RESULT.

rule "Sonoff toggle Teleperiod IR-Partykeller"
when
	Item Sensoren_Status_SonoffHeatingIR changed
then
	if (Sensoren_Status_SonoffHeatingIR.state == ON) Sensoren_SonoffHeatingIR_TelePeriod.sendCommand(20)
	if (Sensoren_Status_SonoffHeatingIR.state == OFF) Sensoren_SonoffHeatingIR_TelePeriod.sendCommand(3600)
end

So, if the Heating is ON the period is 20secs, if it’s OFF, ist 3600secs.

[imhofa (Andreas Imhof)]

I am also using Sonoff POWs with Tasmota and MQTT. I have the TelePeriod set to 60s and think it is a good compromise of regular datas and amount of data Transfers.

Within openhab I use a mean value of the last 5 or 10 minutes to have accurate switching points to define the start ans end time of the washing machine (the same for the tumble dryer).

In my opinion it doesn’t care if you get the machine finished message a few minutes later than it is, AND my wife hates to get false messages…

I use reentrant lock with 10 seconds to debounce my waching machine state machine.

Is this a problem, when i raise the time to 2 minutes?

If i make a thread sleep for that long time, it might be a problem, but how is this with reentrant lock?

My waching machine goes to a very low poer consumption, but sometimes after 1-2 minutes it raises up again one more time and then the washing process is finished. Now i get a message with “wasching machine finished” and some minutes later i get the same message once again.

Is a longer reentrant lock time the right way to solve this problem?

Could this time even be much longer without getting problems?

Hello together,

i have a Problem with:

val Number MODE_OFF = 0
val Number MODE_STANDBY = 1
val Number MODE_ACTIVE = 2
val Number MODE_FINISHED = 3

rule "Washingmachine Consumption State Machine"
when
    Item kel_wmaschine_energy changed
then
    if (kel_wmaschine_energy.averageSince(now.minusMinutes(2)) < 0.2) kel_wmaschine.postUpdate(MODE_OFF)
    else if (kel_wmaschine_energy.averageSince(now.minusMinutes(2)) > 10) kel_wmaschine.postUpdate(MODE_ACTIVE)
    else if (kel_wmaschine_energy.averageSince(now.minusMinutes(2)) < 5) {
        if (kel_wmaschine.state == MODE_OFF) kel_wmaschine.postUpdate(MODE_STANDBY)
        else if (kel_wmaschine.state == MODE_ACTIVE) kel_wmaschine.postUpdate(MODE_FINISHED)
    }
end

I get the following error when the rule is running:

2018-05-29 22:13:44.520 [WARN ] [nce.extensions.PersistenceExtensions] - There is no queryable persistence service registered with the id ‘rrd4j’

I did not install “rrd4j”, I use “InfluxDB”.
Is there a way to fix this with influxDB or do I need to install rrd4j?

Unfortunately, the following does not work with “InfluxDB” either:

…kel_wmaschine_energy.averageSince(now.minusMinutes(2), ‘rrd4j’)…

Please help, I despair at the moment

PersistenceExtensions

please read the docs on persistence: Persistence | openHAB

tl:dr>

• Persistence | openHAB
  yours is probably on rrd4j
• Persistence | openHAB
  “These extensions use the default persistence service. (Refer to ‘Default Persistence Service’ above to configure this.) You may specify a different persistence service by appending a String as an optional additional parameter at the end of the extension.”

Sorry, for the late replay. After i set persistence to influxdb it works.

But now I have another problem, after an update to Tasmota 6.01, the measurements have become worse. With the Tasmota version 5.11 POW has always show (in standby) stats between 0W and 1,2xxW. Now (washing machine switched on) is always drawn to 0. So the machine does not change from Active_Mode to Finished_Mode anymore, because openhab dont update energy-item.

Does anyone have an idea for this?
