Thank you so much thgoebel - I would never have worked that out just by looking at the instructions - but it is now working perfectly.

Thanks once again!

I have wired up a new Plus1according to the Fig 2 in the user manual, with a 12vDC input going to 12v, and GND going to both SW and GND on the Shelly. I can control it via the app over wifi etc, and the relay "clicks" in the usual manner.

BUT, putting a multimeter across the 0 & 1 outputs no 12vDC output happens, and I can't work out why. _Sometimes_ a _very_ brief and _very_ small voltage is detected when I activate the app, but I think that this may just be "noise".

I have tried changing the Settings / Input Output / Relay Type etc, but no combinations cause the multimeter to register an output voltage.

Any ideas gratefully received,

TIA

I have many Shelly devices on my network, but I can't get this Shelly1 to connect properly, and can't work out why. This is what I have done ...

1. Turned off 5G radio in my Unifi WLAN
2. Did the "5 click" reset of the Shelly1 just after powering it up
3. Found the Shelly-xxxxxxx SSID on iOS device & joined it
4. Goto 192.168.33.1 within Safari app

At this point I can see & interact with the device, and can remotely trigger the relay (clicking sound). I can change the name etc etc. I then ...

Clicked on Internet / Wi-Fi Mode & put in my WLAN SSID & password, and I get a “The device will try to connect to [WLAN SSID]" message

I then switch the wifi on my iPhone to my home WLAN SSID; the device (with its new name) appears within the Shelly dashbaord. BUT ...

1. On iOS it says Pending Connection
2. On macOS it says Device is offline

What might I be doing wrong? This simple task is driving me nuts !!!

TIA

Thank you both; I think I have now solved the problem

I couldn't find any of the "works with Shelly" PIR sensors in the UK, so took a chance and bought two new PIR sensors - one didn't work, but one did !!!

FWIW, these two did NOT work

But this one does

I am not sure what the technical differences are, but I am now happy!

Once again, many thanks !

This is what the Shelly reports through to HA, with the button set to "Activation Switch". (If I change the button type to Detached & reboot, no difference in behaviour within HA).

The 6th entry changes from off to on, and from on to off, when I tap on. the button within the Shelly app. But none of the entities change when the PIR detects movement (although the SW wire from the PIR is "hot" when movement is detected, and "cold" when no movement. The PIR "clicks" at the start & end of movement detection.

The wire between the capload and N is _always_ "cold".

It makes no difference if I remove the left hand vertical L wire (shown connected to I in the diagram above).

If a signal is present at the SW input, various actions can be triggered or evaluated in HA.

That is certainly what I had hoped; but none of the 9 Entities in HA change "state" when the PIR is activated. I wonder if this is because SW wire from the PIR is an "input" rather than an "output" - as viewed by the Shelly?

If not, have I wired it up incorrectly (see diagram above), or is there something else I need to do?

Many thanks!

What I would like to achieve is getting a notification within Home Assistant whenever a weatherproof PIR detects motion. I thought that I could do this by connecting the PIR to a Shelly device, which would then report a state change (ie off / on) through to Home Assistant.

I now have the PIR working OK, but have not been able to work out how to get the activity through to Home Assistant. If a Shelly1 can't do this, a second idea would be to use a ShellyPM or ShelleyEM to detect the "state change" of the SW wire instead. I slightly off-beat "solution", but maybe it would work.

OK - that is a shame.

Would using a ShellyEM or ShellyPM work? Perhaps I could "monitor" the current in the PIR SW wire, and when above a set threshold activate an automation within Home Assistant?

(c) Proposal (b) plus a very well isolated (!) resistor inserted in the connection between L1 and SW is another means to solve the issue. Wattage of the resistor may be 1/2 W or 1/4W, resistance 500kΩ to 1MΩ.

Thank you very much for your help - I have made _some_ progress, but am still not quite finished ...

I have wired in a capload ( see https://www.tlc-direct.co.uk/Products/DNCAPLOAD.html ) as shown in the diagram below. Now, the switched live wire from the PIR is only "hot" when movement is detected (which is what I would want).

But ... whilst the "state" of the Shelly within Home Assistant changes from off to on when I click on the button within the Shelly app, this state change does NOT occur when the PIR is activated. I have tried using Detached Switch _and_ Activation Switch within the Shelly app, but this doesn't help. I have also tried removing the wire between L and | (left hand vertical brown wire).

Any ideas how I can change this? I really want the state change to happen when the PIR activates.

Many thanks!

I want to attach my waterproof PIR to a Shelly1 so that I can be notified 24/7 of movement on my drive (through a "state change" within Home Assistant.)

There is no other load (ie a light) on this system.

The PIR has 3 wires ... N, L and L1 (switched live). When I power it up the L1 wire is only powered when the PIR is activated. This suggests it is working.

But when I connect it to a Shelly1...

N > N

L > L

SW > L1

... nothing happens on the Shelly1. I have set the Shelly1 as follows...

• Activation Switch - use it for motion sensor. Any input turns "ON" and resets Auto OFF timer.
  
• AUTO OFF - When On - Turn Off After 5 seconds

The Shelly1 is working in all other respects. What might I be doing wrong?

Thanks!

My Shelly devices need rebooting whenever power is restored after I have a power cut; now that the option to enable the "soft reboot" is no longer working, is there a way to get around this issue? I believe it is because the Shellys "wake up" before my wi-fi access points reboot - but may be wrong.

It is a real pain to have to power down / power up all of the devices as they are spread all over the house & barns.

TIA

Hi, I have been using an EM for several months now, monitoring the power cable going to a robot mower charger / base station. From the myShelly screenshot below, what do the various values mean?

The -65 W will be the current draw (the mower is charging), and that makes sense.

The Returned - is presumably the cumulative number of Watts that has been measured since install?

If so, then the Consumed is presumably zero because no back feeding of power ever occurs?

I also bring the data in to Home Assistant, and that gives the data below. But I am not sure what is meant by Energy and Energy Returned. Or why the Power is different from the -65 W in the first screen shot.

Any help in explaining the data would be much appreciated.

Many thanks - I hadn't done that before, but have now and hopefully that will help. Thank you for your help!

The UK has suffered a lot of power cuts recently & I find that many Shelly devices fail to reconnect after power is restored. It _might_ be that they come back alive _before_ the wi-fi access points they connect through come back online, but I am not sure.

Is there a way to make the offline > connecting > online more robust?

TIA

Many thanks - all working well now. Very grateful for your help

I have two low energy spot lights on a barn that are controlled by two separate PIR movement sensors - with both lights coming on when _either_ PIR is activated. There is no "physical" On/Off switch. I want to add a Shelly1 so that when the Shelly1 is OFF the lights will obey the PIRs, and when the Shelly1 Is ON the lights will come on / stay on.

I tried the wiring as shown in the attached image, and whilst the Shelly1 relay works fine (controlled from the iOS app), the lights are always on even though the PIRs were not activated. How else should I wire up the Shelly1 ? Perhaps the "switched live" magenta line should be connected to "Sw" rather than "1" ?

Many thanks. (And for the avoidance of doubt, I _am_ taking great care with isolating everything when working on it). Ignore the green text at the bottom of the attachment - that is how I want it to work in future!

OK, comparing these figures with the Shelly dashboard, it would appear that the PV Energy (6.29kWh) is the amount of energy the Inverter has consumed since installation, and the PV Energy Returned (247kWh) is the energy generated since installation.

How can I "capture" the Energy Returned today? This is perhaps a question for the Home Assistant forums, but I'll leave it here now.

Many thanks,

I have a Shelly EM running, currently only measuring one "feed" - two PV panels on the roof.

The Voltage is obvious; the PV Power & Power Negative rounded are effectively the same thing, and are the real time generation values in watts. The Rounded feed was created by me.

But what are the first two?

I'd like to think the PV Energy (6.29) is Today's total production, but that isn't the case - if I look on the adjacent non-smart meter the panels have produced less than 0.5kWh so far today.

And perhaps the Energy Returned is the cumulative total since I wired up the Shelly EM?

With the Home Assistant "Energy" module, I am able to include the PV Energy and the PV Energy Returned feeds, but I am not convinced either are particularly helpful.

Any thoughts? Many thanks!
