Support for "Sonoff Pow"

---

will this work with the SONOFF POW?

Hi,

any updates on how to use sonoff pow without mqtt?

I have forked this into a new topic. Generally, it should work with EspEasy, however, I am not sure you can use the power metering feature with EspEasy. The latter has been confirmed to be supported with Espurna, an alternative firmware to EspEasy. You can find some details in the following thread.

Hi,

I got my sonoff pow this morning and finally can test it.
I flashed this firmware on the device: Sonoff-Tasmota

It’s possible to toggle the switch an read informations like volt, ampere etc…

Example:

    {
      "id": "sonoff_2",
      "name": "Test WLAN Switch",
      "class": "ShellSwitch",
      "onCommand": "curl --silent http://ip-address/cm?cmnd=Power%20on",
      "offCommand": "curl --silent http://ip-address/cm?cmnd=Power%20off"
    },
    {
      "id": "sonoff_2_voltage",
      "name": "Sonoff POW Voltage",
      "class": "ShellSensor",
      "attributeName": "voltage",
      "attributeType": "number",
      "attributeUnit": "V",
      "command": "curl --silent http://ip-address/cm?cmnd=Status%208 | grep 'Voltage' | cut -d ':' -f7 | cut -d ',' -f1",
      "interval": 60000
    },
    {
      "id": "sonoff_2_watt",
      "name": "Sonoff POW Watt",
      "class": "ShellSensor",
      "attributeName": "watt",
      "attributeType": "number",
      "attributeUnit": "Watt",
      "command": "curl --silent http://ip-address/cm?cmnd=Status%208 | grep 'Power' | cut -d ':' -f5 | cut -d ',' -f1",
      "interval": 60000
    },
    {
      "id": "sonoff_2_amp",
      "name": "Sonoff POW Ampere",
      "class": "ShellSensor",
      "attributeName": "ampere",
      "attributeType": "number",
      "attributeUnit": "A",
      "command": "curl --silent http://ip-address/cm?cmnd=Status%208 | grep 'Current' | cut -d ':' -f8 | cut -d '}' -f1",
      "interval": 60000
    },

Looks like this:

Nice. Regarding the ShellSwitch I think you can possibly also provide a “getStateCommand” to recognize state changes, e.g. when the push button is used or the it gets switched from another control point in case you run multiple pimatics or other applications

@mwittig Yes, I’m working on the “getStateCommand”

I can get an result with the command:

curl --silent http://ip-address/cm?cmnd=Power | grep 'POWER =' | cut -d '=' -f2

Output: OFF or ON

The ShellSwitch can only return on/off, true/false or 1/0 as string.
At the moment I’m trying to “convert” “OFF” to “off” and “ON” to “on”…

Try to add the following at the end of the command sequence | tr A-Z a-z

Check if trcommand is installed on your Raspi. If not you need to sudo apt-get install coreutils

@mwittig
Works, thanks!

curl --silent http://ip-address/cm?cmnd=Power | grep 'POWER = ' | cut -d '=' -f2 | cut -c 2- | tr A-Z a-z",

thx for this command, it works very well

Hello, I have a problem with the issue of the consumption. I have copied your query and have inserted. Then the ID changed. But my result is not good.
I agree only “unknown” indicated.

Which mistake have I made that I get no announcement of the consumption?

Hello, over again,
my problem has taken care. In the meantime, I get the data indicated. I had a small mistake in the query. I did not have the quotation marks remove

But something else. Can I also let indicate the consumption for the moment?
