HTTP Binding Tasmota 4-CH Device

[yaya]

Hi There,

I am trying to connect my Sonoff 4-CH Switch (running Tasmota Firmware) to my openHAB 4 Server.

If I do use these URL, I can user the Switch:

Status: http://10.1.1.147/cm?cmnd=Power2
ON: http://10.1.1.147/cm?cmnd=Power2%20ON
OFF: http://10.1.1.147/cm?cmnd=Power2%20OFF

My Things Config with Channel looks like:

UID: http:url:f26926a118
label: Terasse Licht
thingTypeUID: http:url
configuration:
  ignoreSSLErrors: false
  baseURL: http://10.1.1.147/cm?cmnd=Power2
  delay: 0
  stateMethod: GET
  refresh: 30
  commandMethod: GET
  timeout: 3000
  bufferSize: 2048
channels:
  - id: Power2
    channelTypeUID: http:switch
    label: Terasse Licht
    description: ""
    configuration:
      onValue: "%20ON"
      offValue: "%20OFF"
      escapedUrl: true 

I am adding an Item (type:switch), but I can not activate/deactivate the switch - nothing happens.
I’m sure I miss sth. but after 2h I really prefer to get in touch with the community

appreciating your help

Hi, why are you using the http binding ? The “usual” way would have been either to use mqtt (which implies a mosquitto broker), flash the sonoff with esphome (and use the new esphome binding), or even use the sonoff firmware (there’s also a binding for that).

I had several problems with the http binding whenever I used “special” characters such as %, so I’m using the SmartHome J/HTTP Binding instead.

Right now there is the Tasmota Plug binding but it currently supports only one channel. I think it could extended to 4 channels.

Tasmota Plug Binding [3.2.0;4.0.0)

[tasmota] As of OH 4.1.0 M4, this binding is now included in the official openhab-addons repository. I made this very simple binding to easily connect Tasmota flashed smart plugs to openHAB without having to setup mqtt or utilize complicated http binding item configurations. Plugs with up to 4 relay channels are supported The plug must report the status of the relay via the url http://$PLUG_IP/cm?cmnd=Power in order for the binding to work. Supported Things There is exactly one supported th…

Thanks, I was not aware of this binding. But I prefer to have the web interface disabled which rules out http commands. And when I enable web interface it is protected by userid:password

Just a suggestion, you may add pulsetime support to your binding.

[mlobstein]

The marketplace binding was updated to support channels 2,3 & 4.

[yaya]

Wow guys - you are amazing.

Actually I was not successfull with mqtt (mosquitto was working with device - tested with mqtt explorer).
But I was not able to find the correct config within openhab.

I will check the plugin in marketplace by next week And will Come back with a Resultat.

@mlobstein: Great job!

as there is no kudos without a question mark:

Maybe you are also able to expand that binding to read also other (mostly) values from Tasmota like temperature, pressure a.s.o. ???
I run a LOT of Tasmota-Stuff here, which not only have switches, but also provide other information and I would love to have them integrated without MQTT.

The issue might be, that it be not easy, as one do not really know, what kind of data is provided. I even do not know (as I´m not a coder), whether it is possible to get the data via the api (and how). Nevertheless, as said, I run a lot of them and can help with testing and proves.

[mlobstein]

Good idea. The only issue I see is that there are many different types of data provided depending on the device. On mine it provides energy usage information:

I will look into it to see what is possible.
@moody_blue I have added username/password support to the marketplace binding.

[yaya]

the plugin from marketplace works like a charm - many thanks for this!

[mlobstein]

I have added energy monitoring channels to the binding. Can you post the output of this URL: http://$plug-ip/cm?cmnd=Status%2010 so that I can see what the JSON output is for the temperature and other sensors? It should be possible to add those to the binding as well.

[scha (Andreas Schmid)]

I´m in the meantime away from openHAB and changed my whole system at home, sorry.
Nevertheless, this is the requested output of one of these devices

{"StatusSNS":{"Time":"2024-03-12T21:34:49","ENERGY":{"TotalStartTime":"2022-12-30T14:11:40","Total":126.659,"Yesterday":0.015,"Today":0.013,"Power": 1,"ApparentPower": 2,"ReactivePower": 2,"Factor":0.26,"Voltage":233,"Current":0.010}}}

The device is one of them: https://www.amazon.de/Tasmota-Steckdose-NOUS-A1T-stromverbrauch/dp/B0054PSI46/ref=sr_1_1_sspa?crid=3G3RMYHORAIYZ&dib=eyJ2IjoiMSJ9.ixPcv0ORuHb3cIpoSsQORHt89Ojwyt-spa0QvBZEPcftLJAJ2k-CVlb5ic65TkfKkqgYqKv5TrCB9-ZQ9k4Jyfe6CEtHY4WqjP92F4w5jmFsNu-2kfCANRhw-QFS_48aA2ba8pUKbqqtA8hI02d8d7BeoaSheQFpf7ZBZvaEMj-XdNHCaepQ5MNEE_HVxU0P_U_Joht5YvG_8GTVmksLcukzfU7kD2rf4zrmCdLXguNYU2HLKRsl6y9Xa3JNk_rwxKkX649RSypcZVNzcoxN-eGLcMxKzmwddV97LBERGVM.H1BNztvZrFJTr-lxVuC_Y6RXtOctbzCYru6TaMwR5bo&dib_tag=se&keywords=nous+tasmota&qid=1710275771&sprefix=nous+tasmota%2Caps%2C136&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1

[mlobstein]

Good. That looks exactly like what mine outputs and what was implemented. If you have a chance, please post the output of the one with a temperature sensor.

Below is a compiled jar with the new energy monitoring channels: https://github.com/mlobstein/openhab-addons/releases/download/v4.2.0-snapshot/org.openhab.binding.tasmotaplug-4.2.0-SNAPSHOT.jar

[scha (Andreas Schmid)]

I can give you that:

{"StatusSNS":{"Time":"2024-03-13T07:05:21","DS18B20-1":{"Id":"0317714BBCFF","Temperature":32.6},"DS18B20-2":{"Id":"031771786EFF","Temperature":48.7},"DS18B20-3":{"Id":"031771805BFF","Temperature":36.1},"DS18B20-4":{"Id":"0317718310FF","Temperature":36.9},"DS18B20-5":{"Id":"031771A53AFF","Temperature":49.3},"SR04":{"Distance":52.2},"TempUnit":"C"}}

or that:

{"StatusSNS":{"Time":"2024-03-13T07:07:52","DS18B20":{"Id":"000006150809","Temperature":9.6},"BME280":{"Temperature":12.2,"Humidity":47.1,"DewPoint":1.2,"Pressure":963.4},"SR04":{"Distance":32.5},"PressureUnit":"hPa","TempUnit":"C"}}

[yaya]

I have this device:

4CHR3/PROR3 - SONOFF Official

my result for that is - anything wrong here? running latest tasmota 13.4.0.2:

{
    "StatusSNS": {
        "Time": "2024-03-14T06:50:35"
    }
}```

[mlobstein]

I don’t think all devices contain the energy monitoring bits.

[mlobstein]

@moody_blue I made a PR to add PulseTime:

[tasmotaplug] Add PulseTime channels

Try this test jar (rename to just .jar):

org.openhab.binding.tasmotaplug-4.3.0-SNAPSHOT.jar.txt (22.9 KB)

[moody_blue (Hugo)]

Thanks. I don’t know what is your criteria to organize channels in advanced or not. In my opinion pulsetime is not advanced (it exists in all switch devices), but energy & power are advanced (only exist if the device has such sensors).

Pulsetime is working as intended but when the switch goes back to off sometimes OH is not updated and the switch item remains in ON. Also, if I use toggle in the tasmota console the status is not reflected back in OH.

[mlobstein]

OK, I removed the advanced=”true” for PulseTime and updated the jar. You can set the Refresh Interval configuration parameter to something smaller like 5 seconds so that the switch state will update sooner,.
