Compatibility request: LinknLink eMotion Pro (mmWave presence sensor)

[NeosS]

Hi everyone,

I would like to know if the LinknLink eMotion Pro (a mmWave presence and motion sensor) can be integrated with Homey Pro.

This device connects via Wi-Fi (2.4 GHz) and officially supports Alexa, Google Home, and Home Assistant (through MQTT / Motion2MQTT). However, I couldn’t find any information regarding Homey compatibility or an existing app for it.

My questions are:

• Is the LinknLink eMotion Pro currently supported by Homey (officially or via a community app)?

• Has anyone tried to connect it to Homey Pro using MQTT or another integration method?

• Would it be possible for developers to consider adding support for this device in a future update?

This sensor is quite interesting for smart presence detection, and it would be great if it could be natively integrated into Homey flows.

Thanks in advance for any insights or guidance!

The sensor is Sensor LinknLink Pro Sensor

In this video a review is done, for me it’s very interesting

and Home Assistant (through MQTT)

Ah, then it’s supported and ‘quite’ easy, by using the Homey community apps
MQTT Broker, MQTT Client & MQTT Hub.

With MQTT Hub you can create a virtual device which takes and sends commands per MQTT topics.

An example of how this works:

[Tutorial][Pro] Basic MQTT setup & connect Itho Daalderop NRG.watch interface

This tutorial is about setting up a basic MQTT system. (and yes I know there’s several other MQTT tutorials around ) Additionally, it tries to explain how to connect a system like the NRG.watch interface for Itho airboxes (no need for the Homey NRG.watch app) Feel free to add missing info, or correct any possible errors. (This is a wiki) Homey: 1 Install 3 MQTT community apps: MQTT Broker [1] MQTT Client MQTT Hub ¹) The broker may run anywhere, but we stick to Homey for now …

Thx Peter

I’ll read it all right, but ideally there’d be an official app—the sensors are very good and it’s a cheap alternative to Aqara.

Thanks! Yeah, I get that, but in the mean time you can use it already
I was triggered by MQTT and this always works @ Homey.

App requests usually go to https://request-a-brand.homey.app
or
[Requests] Homey Pro Community App Requests

BTW This €16 device also seems a nice presence sensor, supported by the ‘official’ Sonoff app:

SONOFF Zigbee menselijke aanwezigheidssensor | SNZB-06P - Opencircuit

Opening this post again, I’ve installed everything related to MQTT, and everything is OK.

With MQTT Explorer, I can see the device which is this:

home/e04b4101a8420000000000009cac0000_0/

And all the topics, how do I add it to Homey?

If it is of any interest, I am working on an app for the eMotion sensors. The app has a built in MQTT broker, but it can also connect to an external broker if required.

It’s a simple setup if you use the internal broker as you can just install it and add devices like normal.

ATM I just have support for the eMotion Pro and eMotion Ultra. I am just waiting for an icon from Athom and then I will publish the app.

Note: you will need to configure the sensors in the LinknLink app to publish to the broker.

Ouhhh great new Adrian
