  • Getting both positive and negative power readings for devices monitored via Pro EM-50

    Didn't find a subfourm for Shelly Pro EM-50 devices, so I'm adding a new discussion here.

    This week I've isntalled my latest Shelly device to my home newtork, It is a Shelly Pro EM-50 that I intend to use to monitor the power consumption of my induction cooktop and hooven appliances in the kitchen.
    I've installed it in the secondary switchboard in the kitchen, and everything seems to be working almost fine...

    I learned since I installed my first Shelly EM device, that after installation if getting negative readings, I need to invert the orientation of the current transformers or clamp sensors giving negative values.

    In the present case it happens that I also had to make such correction, although I sitll get a positive reading in the range of KWs when the respective kitchen appliances are working, but also negative readings when the appliances are not working (aprox. -17W for the cooktop and very small negative readings for the hooven), which jeopardizes the total consumption values over time.
    - What could be the problem?
    - Is there any way to calibrate the zero?
    - Could it be related with electrical wires or sensor cable routing inside the switchboard? The available space is quite thight and I'm affraid there is nothing I can do...
    Have another Shelly Pro EM-50 installed in the house main switch board and didn't observed such behaviour. Everything is working fine with that one!


    PS: BTW, much better if it would be possible to configure the reading signal (-/+) in the device settings via app, as inverting the sensor is not always that convinient because of routing issues in thighter spaces...

  • Shelly devices ocassionally "die", remaining offline and without collecting measures.

    I have two TP-Link Range Extenders (TL-WA850RE) in my home network.
    Have them for many years, hence they are not the newest thing in market... but still being sold.
    Currently in the process of wiring one of them via ethernet Cat.6, directly to the router, in order to switch it to AP mode.

    Nevertheless the Shelly devices where this issue happened are close and served by the main router.
    Not sure what should I do in order to check if there is a problem with my network. :/


    As for the device being offline or not, at least for sure it stops synching measurements with Shelly Cloud, and these are also not synched when the device is "forced" back online. Not to the respective time slots, neither to the latest time slot (when it reconnects), so it seems the device is frozen and actually not measuring anything.

  • Shelly devices ocassionally "die", remaining offline and without collecting measures.

    I'm experiencing sporadic issues with random shelly devices.

    To be honnest this is not something I was not expecting, but still very annoying and inconvenient for a commercial product.


    Very occasionally one of my Shelly devices "dies" which usually I only notice after a few days.

    When acessing the Shelly app, the device in question shows up as offline and so it remains "forever".

    The last time time this occured and because the realy is not easily accessible, I managed to solve the situation by power cycling it via the respective circuit at home electricity switchboard.

    Unfortuantely the measurement data for the period the device was dead, seems like it was also not collected, or at least it was lost at some point and never uploaded/synched into Shelly Cloud.

    Anyone experiencing the same sort of problems?

    Any advice?


    I'm just nervous of thinking this may happen one of these days, to a relay deeply burried into a wall socket behind heavy furniture rather than any other easily accessible...

    Today it happened with a "Shelly Plus 1PM".

  • Shelly Duo - RGBW E27 appears to reset itself after some days off

    I've a "Shelly Duo - RGBW E27" bulb, that is not used very often. It may stay switched off for several days or even a couple of weeks.

    The bulb uses to be set to light as White (4750K), although when I light it after several days off it uses to lit in blue and always remains offline at Shelly app. It looks like that at some point in time the bulb did reset itself.

    To overcome the situation I need to add it again via WiFi, as if it was a new device, and redo at least some of the configurations (e.g. the color).

    Anyone with the same problem?

    Any advice?

  • FW upgrade often produces no effect

    Hello,


    I've just upgraded FW of all my Shelly devices to FW version 1.0.8.

    I observed not only with this upgrade but with previous ones as well, that often the upgrade produces no effect. Once concluded and device gets connected again, the FW version remains the same.

    Some devices may take 2 or 3 attempts to get the FW effectively upgraded.

    Is it normal? It's only me? Or there is some advice to make it work mre reliably?

  • Error "Triying to add unknown device type" or "Pending connection"

    Thank you for the hint!
    I never used the WEB-UI before, so I went to find some informatiuon on how to use it. :)

    I had updtate my "Shelly Pro EM 50" at 03.Oct to latest official firmware version available - 1.0.5.

    I've now updated it to 1.0.6-beta1 via WEB-UI.

    After a few attempets and having always reseted the device, I've also always gotten the "Triying to add unknown device type..." error message.
    Maybe if I continue trying, I'll also get the other message... "Pending connection".

    Anyway, the latest beta doesn't seem to solve the issue I'm experiencing.

    Should I open a ticket to official customer support?

  • Error "Triying to add unknown device type" or "Pending connection"

    I'm having an hard time with a recent launch and my latests Shelly device: "Shelly Pro EM 50"...

    I bough this device a week ago which I initally added successfuly to my app/account. Not at first but after a couple of attempts...

    Today suddenly this device widgets' started not responding in my Android app, and also didn't display any measurement information. At first I thought it was an app or Shelly cloud problem, but then realised that if I touched other widgets first, these were working properly, and it was when I thouched any of the two "Shelly Pro EM 50" widgets that the app becomes irresponsive.
    So I deleted the device and tried to add it again... and that's when everything became even worse!

    At my home I've a main AP from the house router and then I've two wireless extenders from TP-Link, with the same SSID.

    When trying to add my "Shelly Pro EM 50", I've tried two different things and none of the seems to work, besides I'm not sure which one should be the most reliable or adequate.
    As my attemps to add the device do not fully work, I need to reset the device (10s button press) between each attemp, otherwise it is not even listed to be added.

    Sometimes I try to add the device through the extender AP which is closest - By selecting the SSID associated to the respective MAC Address.
    Most of the time I get a "Triying to add unknown device type. Please try again to confirm. If this error persists contact support to verify the device authenticity." error message.

    Sometimes I try to add the device through the main router which is farther - By selecting the SSID associated to the respective MAC Address.
    Most of the times I get a screen with "Pending connection", sometimes also the "Triying to add unknown device type..." error message as above.

    Any idea how can I resolve this annoying "Pending connection" state?
    For the time being my "Shelly Pro EM 50" rests useless... :(
    And I have a second one that I bought yesterday to install as well. I'm looking at it... wondering...


    Thanks and best regards,
    Fernando

  • Voltage measurement not displayed

    I've both "Shelly Plug S" and "Shelly Plus Plug S" devices.
    As visible in the image below, the first one only displays the current power and the second displays current power + voltage.
    I can't find any mention to such difference in the technical specs of these two plug types.

    Is it really the expected behaviour, or am I doing something wrong in the app?

  • Delete consumption history

    You still see the data even after reset because it is stored in the cloud associated to your device ID and your account. Hence when you add the device again, the historic data comes back...

    You can contact official Shelly support and ask them to wipe cloud data (historic) from your decice.
    I did it myself and it worked great!

    Like you probably others also change devices location frequently (at least those of plug type), hence the ability to wipe cloud data directly from the app would be a valuable feature. It should be possible and easy to implement!

    Hope it will become available in a near feature!

  • Wipe measurement data from a Shelly device from cloud

    Imagine one wants to reuse a Shelly device to control and measure a new appliance.
    Is there a way to wipe this device measurements stored in the cloud?
    Old data is not applicable to the new appliance and it may be misleading.

    I do not mean a Factory Reset of the Shelly device (one may want to preserve some settings), which btw I don't know if it would wipe the data anyway.

  • Shelly Plug S suddenly went offline and connected appliance has no power

    After having a Shelly Plug S working fine for about 3-4 weeks, I suddenly noticed in the app that it turned offline.
    Went to check the appliance connected and it also had no power anymore.

    Looking at the plug it self, the LED is blinking blue (slow blink as it seems). Dicconneted it and connected again, but still no power, blue led blinking and offline in the app.

    After pressing the button, the appliance turned on, and appear with red led (still) and blue led (blinking). Still offline.
    How can I resolve this this?

    Do I need to perform a factory reset?
    It wouldn't be convinient to configure it all again. :(

    Fortunately this is phisically acessible with ease, but if it was a module installed behind a power socket I wonder how to handle it easily...


    PS: The firmware version was the latest (updated yesterday 13.Sep.2023). Maybe this FW version did introduce some new bug that caused this to happen.

  • How to connect when I inted to monitor power consuption only?

    I've installed it and it is working! :)
    As a matter of curiosity I tested if I can switch off via app, with my setup (wire between L and SW + "Auto On" + PIN to switch off).

    App returns the message "Something went wrong!"

    Is this correct?

    If I want to keep ability to switch off via App, should I remove the wire between L and SW?

    If so, shouldn't the app be more explicit telling the reason why the operation can't suceed? All the SW and HW configurations should be known by the app.
