The error: 

Network steering was not successful (status: ESP_FAIL)

I wonder if anyone else have experienced something similar. The device had switched off all 4 sockets without any foreseeable reason. And it kept them off until manual activation.

Is there any possible reason this to have been part of an expected behavior? Or I should consider it as a bug?

I have two power strips for just over a day now. Only one of them had this behavior once.

It is connected to WiFi (for device's UI usage) and it is also connected to Home Assistant via Zigbee (ZHA). Only two of the sockets are part of automations that control their status. The other two sockets switches are not even mentioned in any automation or dashboard. I do monitor the power usage of all 4 sockets.

The devices doesn't report any new firmware updates, and I assume this one is the current one: 1.7.99-powerstripg4prod1

Best Regards!

seems that without known reason values reported via zigbee are stuck until device reboot.

I see via mqtt that values reported are not correct as socket is off and still reports 42W. (it's just an example of many others).

Even on WebUI it's reporting that there is power on turned off socket.

What should I do?

Thanks

am i missing some special setting for this type of device or it simply does not send internal temperature over mqtt ?

documentation says that it has internal temperature sensor and all other shelly plugs and relays i have send internal temperature in something like <mqtt_prefix>/status/switch:X

does it send internal temperature over other supported protocol ?

thanks,

Are there any holes on the back so that the power strip can be mounted?

As a power user (Home Assistant), I need to use the LED rings to show different statuses (like Tempo electricity days or specific appliance states). Please upvote this if you also want the API to support switch:1, switch:2, and switch:3 as advertised!

It would be really cool if the LED could be changed via API. For example: to display server status directly.

Error / no error / error gone, and so on.

Thanks

Best regards

is there something i do wrong here ? 

Does anyone have a similar problem or a solution for it?

And the Coffee machine at 1.4kW color is only yellow (so it should be possible to have different colors for each plug) 

I'm disappointed not being able to setup the colors at the plug level 😢 
 

It is a very smart one since it give you 4 CEI 23-50 P 40 sockets and fit in a standard 503 wallbox used normally for one or two sockets.
Shelly could make the wall version of power strip in two versions:
one with all the four socket (could be a problem to squeeze all the relays inside) independent, another that probably would be even more sueful and cheaper having socket 1 and 2 controlled by one channel, socket 3 by second channel and socket 4 always on. De facto a 2PM put inside.
With clever squeezing of internal additional components, could be also a multistandard socket, accepting also standard IEC 60906-1 and SN441011 (it may easily have more ground connections, just by making addinonal holes and modifying the blades of the contacts, in the same way that is made for the power ones to accommodate CEE 7/7 and CEI 23-50 S 17 )

User interface

 

Inputs

• One push button for each socket

  • Press to turn the output On/Off.

  • Press and hold to turn Off all 4 sockets on the strip

• Press and hold push buttons 1 and 4 on the strip

  • For 3 sec to check status (Possible only when the outputs are Off).

  • For 5 sec to reboot (Possible up to 60 sec after plugging in the device to the power grid/power supply).

  • For 10 sec to factory reset (Possible up to 60 sec after plugging in the device to the power grid/power supply).

• Press the control button for the desired socket 5 times in quick succession 🔲 → 🔲 → 🔲 → 🔲→ 🔲 :

  • To switch the Device from Matter firmware (default) to Zigbee firmware.

• Press the control button for the desired socket 3 times in quick succession: 🔲 → 🔲 → 🔲 :

  • To activate Zigbee commissioning mode. This enables the Device to connect to a Zigbee network (pairing mode).

 

If these were true would that means that the buttons hare hardwired to such functions or that these are the default functions, but you may set as detached as in normal shellies (so you cannot use two three and long click to set different timing or to send controls to other devices ?)
Would this mean that each of the four sockets may use matter or zigbee firmware, indipendently by the others ?
Or the document linked was a prerelease, still to be refined ?
