Due to the fact, the length of an output pulse has to be determined to evaluate the distance information (range from 0 to 35 milliseconds), also the URM09 sensor will NOT be supported by the Shelly “plus” Add-On

Hi thgoebel,

I am not quite sure about that. Because in the official Shelly Plus Add-on Launch video (at 31:10) you see them demonstrating an ultrasonic sensor. When I saw that at the time being, I ordered my add-ons right away... I had not paid attention very well while watching this video for the first time (because it goes rather quick), but when you look at the wiring a bit more in detail, I think it looks like this:

So based on all I mentioned above already, I think this currently only works for ultrasonic sensor that have an analog output signal (which they measure with the add-on ADC converter).

BTW I have submitted a feature request to ask whether something like this could be implemented in the plus add-on. That one data pin can be used for the trigger pulse, and another data pin for the echo pulse (and the add-on calculates the time difference). But I didn't get any feedback. It is also not clear to me if I can see these feature request somewhere online, to find out if someone has responded...

Now I am confused. Some Shelly related sites (like e.g. this one) sell hc-sr04 sensors "for addon plus". From that I would expect it should be working together?

I would appreciate a lot if somebody could illuminate me.

Because I received yesterday a series of Add-on hats as a father's day present, so it would be awful if I cannot use them...

This facebook discussion mentions that the URM09 distance sensor is supported by the add-on. That sensor has a shared trigger and echo pin, unlike the hc-sr04 sensors

It would have been useful if the documentation had mentioned this...

Looking at the pinout of the add-on, I assume proximity sensors like hc-sr04 will/can never be supported?

Hi all,

Can anybody confirm that this information is still correct. I had ordered a series of add-on devices, because this knowledge page shows "Ultrasonic proximity sensors" in the list of supported sensors. Therefore I thought that the hc-sr04 would be supported. So it would be real bummer if it would not be supported after all...

Thanks!!

BTW when using the same button in the user interfaces in one of my Shelly plug S devices, the corresponding message is immediately published on my MQTT broker...

I had yesterday upgraded the firmware to the latest:

And I see via MQTT explorer that I have recent data from my other Shellies, so my MQTT broker must be working fine:

It now pops up in my mind that there are two differences with my other Shellies:

1) This non-working one is my first Shelly 1 switch (while the others are type Shelly plug S).

2) My wiring of the Shelly switch is not completed yet, so I had tested this by pushing the button in the web interface:

I assume this button will also result via a message over MQTT, since the relay state is changing? Because the relay is activated when I use this button...

Hi Stefan,

Thanks for joining! Here are my settings:

So currently no username/password, until everything works fine. First I had no custom prefix, but that mad no difference. The different values of Max Qos also didn't help.

Dear,

I am using MQTT to get status changes of my Shelly switches.

Using MQTT explorer you can see that my MQTT broker is working fine:

I have now installed a new switch, but it doesn't publish any messages via MQTT when the status of the switch is changed.

The MQTT settings in my Shelly user interface are identical to all my other Shelly switches.

I also tried to (temporarily) enable the debug log, but when the status changes no log is being displayed when I try to display it.

Summarized: no messages are being published when the switch status changes, and also not periodically...

Does anybody has tips how I can troubleshoot this further?

Thanks!!!

Bart
