Shelly BLU Motion is DIGGITY BOMB!

Thanks, that’s super helpful. What HA entity/device event(s) are triggered when there is motion?

KruseLuds · July 1, 2024, 2:12am

Not sure exactly what you are asking but here is how it looks (drilling down and use in an automation):

BTHome integrations -

Here is one of the sensors -

Showing it’s activity -

And then in an automation as a trigger (remember these are just PIR sensors) - showing just the trigger part of an automation:

My motion sensors are all just PIR and as you know those are not perfect for detecting presence, so I only have my motion detectors (re)start timers - that is all they do. When a timer is (re)started, then specific lights go on if not already on, and when the timer ends it turns those same lights off. Then I got fancier and only started the timer if the light had not been turned OFF manually within the last 5 minutes (this stops a situation from happening where someone would turn off a wall switch and then walk out of the room - without such logic the lights would go back on while they are walking out). I also added a dashboard slider for the timer duration, drop downs with “Enabled” “Disabled” to possibly not fire off automations (essentially not (re)start the timer), etc. The lights do not go off immediately when people are suddenly not in the room (but eventually do go off in empty rooms when the timers expire - but because of the timers they never go off while people are sitting in a room motionless either ) I don’t necessarily needs lights going off in a room the instant someone walks out. WAF factor is high… but it was low while I was building things out as the occassional hiccup causes a husband browbeating…

I have learned the WAF is higher if things just work, and also work manually, and I have hidden redundant sensors many places so if one fails things still work, etc. (for example in the above scenario several different motion detectors may call the same automation…)

Love it! Thanks

Sure. I have some spares but have to take the battery out of them so they don’t keep popping up in HA!

Hi,
I have some xiaomi motion sensors for my hallways but occasionally, they fail. Anyway since I have many Shellys already, looks like those are great for my needs.
Question: what is the cool off time? I mean my xiaomi is 5 seconds (hacked) because in a hallway sometimes many family members walk within a 10/20/30 seconds interval and it is nice to have always the timer for 30 seconds.
Not sure I am clear…

KruseLuds · July 24, 2024, 1:28pm

It is adjustable. I have mine set to 30 seconds

fernmac · July 24, 2024, 2:31pm

Thanks, can you tell me the minimum time?

fernmac · July 24, 2024, 2:34pm

Another question: do the sensor needs to be close enough to my raspberry (HA in it), in bluetooth range or I just need say a shelly gen2 (with bluetooth) close enough and then the sensors connect to HA through this shelly or any other closer?
thanks

You can put in whatever seconds you want:

When you add it into the Shelly APP, it shows you all the Gen 2 Devices you have and lets you select which ones would be the gateways for it, I always just pick all of them. Also the app is where you adjust the settings, and when you are setting it up or changing anything on the BLU Motion, you are often asked to press the button inside of it, so keep it within reach until you are done with the config of course.

It would be in the BTHome integration (not Shelly)

I just got an email with this text @fernmac (and others):

Thank you very much for sharing KruseLuds

Hi, I just installed the Shelly Blu Motion with home assistant via a bluetooth gateway of another Shelly and seems to be working correctly detecting all the motion. However I don’t know how to change its settings. In particular I was looking to disable the LED and to change the blind time. I know it’s possible to do that with the Shelly cloud however I have disabled the cloud for all my shelly devices and I usually configure them by accessing their web interface. Is there something similar for the Shelly Blu Motion?

KruseLuds · July 25, 2024, 7:52pm

Good question, I would love to hear anyone else on this forum about it. If you are on the same local network as all of your chelly devices with the Shelly App, you should still be able to see it, no?

Paco1960 · July 29, 2024, 8:31pm

For me the only way to configure Shelly Blu Motion sensors was using Shelly app, and much better Shelly BLE Debug app.
One device became unusable after a few update, and only with latter app was able to recover an easily configure them.

kaharoth · July 31, 2024, 1:13pm

Thank you! I solved my issues with the Shelly BLE Debug app, and for those wondering, no it’s not necessary to have a cloud account to use it.
Now I am trying to understand the best height, position and orientation of this sensor for the best detection. Is the correct orientation the one depicted in the picture printed in the box?

Paco1960 · July 31, 2024, 2:08pm

Sorry, but currently I can’t help you because I’m in trouble as explained in this post https://community.home-assistant.io/t/shelly-blu-gateway-not-discovering-shelly-blu-motion/744004/2?u=paco1960

I hope someone could help me too

I can’t seem to get my Blu Motion to behave correctly. Regardless of the sensitivity settings, it always claims to be detecting motion. 3 mins blind time, and using this script on the Shelly Plus 1pm which is its observer, the light constantly turns off and on every 3 minutes:

github.com

ALLTERCO/shelly-script-examples/blob/ca4ddebc96226e84bd617a2bc4e036f9c966698e/ble-shelly-motion.js

/******************* START CHANGE HERE *******************/
let CONFIG = {
  // When set to true, debug messages will be logged to the console
  debug: false,

  // When set to true and the script ownes the scanner, the scan will be active. 
  // Active scan means the scanner will ping back the Bluetooth device to receive all its data, but it will drain the battery faster
  active: false,

  // When `allowedMacAddresses` is set to null, evets from every bluetooth device are accepted. 
  // allowedMacAddresses: null, 
  allowedMacAddresses: [
    "aa:bc:12:34:56:78", // events only from these mac addresses are allowed.
    "11:22:33:45:5a:bc", 
  ],

  /**

   * @param {Boolean} motion true, when there is a motion, false otherwise. 
   * @param {Object} eventData Object, containing all parameters received from the Shelly BLU Motion device. Example: {"encryption":false,"BTHome_version":2,"pid":16,"battery":100,"illuminance":109,"motion":1,"button":1,"rssi":-53,"address":"aa:bc:12:34:56:78"}

This file has been truncated. show original

I tried configuring the BTHome device for it in HA, which doesn’t seem to fare any better. The entity always claims to be detecting motion, even in a room with the door closed and absolutely no motion.

Up-to-date firmware, so I’m at a bit of a loss. What am I doing wrong?

JC_RFC · October 14, 2024, 4:00am

I have been testing one for a couple of weeks and am not as enamored with them. Setup is awkward (need a separate app), coverage is narrow, and worst of all it has stuck in the “on” state twice already as per:
https://www.reddit.com/r/ShellyUSA/comments/1fjjpcs/shelly_blu_motion_stuck_in_motion_state/

My Aqara P1’s are proving much better thus far.

bilalhp · November 9, 2024, 11:16pm

Can I use Shelly BLU motion sensor without a gateway, i.e. raspberry pi running HA directly capturing the events from that? Is it possible? I am asking because I am new to Shelly ecosystem and I don’t have any other Shelly devices at home (to act as a gateway).

KruseLuds · November 10, 2024, 5:37pm

No, something must act as a gateway - either a USB dongle they sell or any gen2 Shelly device. Better to use a gen2 device like a relay or the like as you are getting more bang for your buck (automating an additional wall switch, for example)
