In and around my smart home I have used RM4 Pros with great success linking to other devices, just recently though, the prices after not getting any lower and competition is coming up with same thing but smaller, extra features and cheaper. This is were this comes in!So this is basically a RM4 Pro but with a mmWave sensor built into the top and comes with what looks suspiciously the same temperature and humidity cable (which is a paid extra with the RM4 Pro). The app also feels the same as Broadlinks app (which is a good thing), with loots of devices you can add as well as manually add your own.I have this integrated with Home Assistant by unlocking in the LinknLink app and then using hacs integration. Motion sensor comes through great (unfortunately not the distance) along with temp/humidity. It was so easy to switch RF and IR devices to using this instead by learning within home assistant and basically replaying to control devices within automation flows. Basically if you are looking at RM4 Pro, don't bother, and just buy this.

*Edit*The linkNlink device is infuriating to work with. Constantly goes offline, constantly acts up and getting it to behave with home assistant is a nightmare. Buy the broadlink and a separate motion sensor. They would be far better for your money.*Original*I have two problems with this. If you have a Broadlink device, they share sister apps(its the same app, but device specific) that work together. You can easily link your Broadlink device to the LinknLink app, it will force an update and kill your Broadlink device. It will do the same the other way around but the motion won't work in the Broadlink app.So at the moment, the LinknLink works fine and the Motion sensor works brilliantly. My broadlink RM4 pro... Dead at the moment until I get a new firmware for it.

Only just got this thing so can't comment on longevity yet. However, the LinkNLink app is easy to configure and it was incredibly simple to pair the device and add IR Remotes to my Alexa setup.I had a few issues configuring the modbus integration with Home Assistant, but the support team at LinkNLink were very quick to reply and assist me with my issues.edit: For those wanting to use the IR/RF Transmitter in Home Assistant, LinkNLink are coming out with an integration but in the mean time adding the Broadlink Integration will work with this device and allow for reading/writing IR signals. Note that when using the Broadlink Integration, the proximity sensor doesn't work out of the box. It might be possible to add that back with Modbus, but I am unable to get both working at the same time.

I had hoped to use this to connect to some kinetic light switches but it's RF detection requires constant signals and switching the kinetic switch on and off wasn't enough for this device to pick up a signal that word work but i'm sure for other cases it will work alright. The humidity and temperature is handy and the motion detection is okay. But i've not been completely sold by the mmwave sensors used in linknlink products, even with some of the newer models.

Just wasn’t as easy to set up as I thought it would be, and the least technical minded will probably struggle to get it right without a few goes at it

Infra red control your home devices ( can learn remote controls and allocated buttons ) ask Alexa to turn on tv etc etcCan make a routine based on temperature/ humidity ( maybe switch on air-con via infrared )Works with Alexa routinesAnd can activate other items it it detects a presence in the room ( human )All these things in one tiny box is amazing top marks !!

Really love how discreet and the linknlink is. The ir blaster works well and I found it doesn't even need to be pointed directly at the tv or sound bar to work. The motion sensor is really effective and instant. What a bargain! Will buy another when we move!

Not as good as i hoped, software buggy and support unsupportive As a RF and IR controller this is good. As a home assistant conected presence sensing device it needs more work. The presence sensor is unrealiable due in part to software bugs. To link with HA you need to unlock the device and this is simply a toggle switch in the settings, however it relocks at random meaning it disconnectes from HA and any automations that rely on it stop working. I have raised this as an issue with the company but have not managed to get anything helpful from them other than it has been raised with the development team but no idea on when or if this is going to be fixed. Also I find the design of the device strange as in the connecttor is on the topmeaning the power supply is expected to be supplied from a socket above the device which makes me wonder why as most sockets are 30cm above the floor, the cable is also very short meaning you will need some sort of extension cable, if you sit the device and a shelf it looks odd because you have the power cable sticking up into the air, and it will need to be stuck down some how, plus it is black which means it stands out like a sore thumb, some really strange design decisions that you don't really appreciate until you try and use it. Binned it. I would have been prepared to put up with most of these issues had they shown any interest in helping, but they haven't met so I've lost interest in this brand Advice stick to well known brands
