Thanks for sharing. It looks promising.
Out of Reward so i can not back it.
Yes, he is not a professional so he doesn’t want to offer more reward than what he will be able to produce.
He said his design will be open-source/open-hardware so you’ll be able to put one together yourself.
I think he might also propose some after he delivered the kickstarter backer (he spoke about improving the assembly process post-campaign).
I’ll try to work on the integration with hass once I receive it

The design appears to be pretty simple. I’ve asked which zigbee module he has chosen, so I can built the usb / wifi module myself.
Anyone ordered / backed the campaign? Would be great if it would be supported.
Yes I ordered it, the complete one with wifi module (I’ll certainly reprogram it to work through MQTT, depending on how complex the pairing and communication is).
Sure the hardware seems quite straight forward, just a zigbee serial module with a serial to USB or a serial to wifi adapter (an ESP).
I think it’s a JN5168, but he didn’t announce yet which exact module he will be using.
The same as used in the Mesh Bee from seeedstudio
The hardest part for his project was to crack the encryption protocol and to manage the different implementation of the protocol used by different manufacturer (Ikea, Philips, Xiaomi, …).
Thanks for your reply.
I’ve seen they are only about 11 euro’s at Farnell.
Found a nice breakout board for this module as well.
I agree creating a MQTT bridge would be the moest preferable solution, straight forward to intergrate into several automation systems, Node-Red etc.
Lets hope the software / firmware will be shared public by the developer, it would enable me to bypass the ghost motion problem I’m experiencing Xiaomi body sensor gateway maybe wrong motion detection
This is really the problem, ain’t it 
It really should not be this hard.
Zigbee alliance really missed a trick with their certification scheme IMO…
An approach with mandated interoperability for a given profile (light, sensor, etc) should have been a must.
Yes, and there is also a private encryption key of some sort that only the constructor is suppose to know.
Thankfully it seems that most of them use the default key, that’s how he was able to pair/use the different protocol.
Have you guys checked the Dresden stuff? They have a Raspberry Pi module and a USB stick that works with their (open source) software. It has a REST API, and supports Xiaomi sensors (not sure if all of them).
Have seen this. I’m thinking about ordering the usb stick.
The rpi shield won’t allow you to sniff the packages while the usb stick does.
What I like is the activity on github. They appear to develop quickly, their software even allows you through update firmware of ikea bulbs for example.
The French guy with his zigate delivers a module including wireless functionality so no controller software or rpi is needed. I must admit I like that to…
However it would be great if Dresden would be integrated into HA
Dresden seems to work with the HA Philips Hue component! I’m tempted to order one too. I didn’t knew about the sniffing difference.
I bought those things a few days back: https://www.gearbest.com/living-appliances/pp_443553.html
But doesn’t seem to be recognized by RM-Pro 
I’ve used a cheap and cheerful option for one button. I’ve already invested in the RFXtrx 433MHz transceiver, and it works with a number of door chimes. I bought a spare bell push for £5, and I’m using that as a light switch toggle.
I have tried the Siemens door bell and it just gives out a number. Every time I use it and on HA it just stays on that number. I also have the RFXtrx 433mhz.
Do you get an entity created in HA? Something like sensor.xxxxxxx_sound?
You might find a blog post I wrote about the doorbells useful - it shows how to take that number, create a device with a more useful friendly name and then have actions triggered when it’s pressed using the signal_received event.
For the light switch, I just use the same sort of trigger with an action that calls service light.toggle on the relevant light.

Thanks
That sorts it out . Nice blog.
Thanks, glad I could help
Cannot find a reference to Xiaomi sensors, where can I find out about that?
They did start to support Xiaomi recently.
But AFAIK the dresen devices are not well integrated with HA (yet).
Some has started building a custom component.
I think there is a lot of potential from this direction, but not mature enough (for me) yet.
Are there any new products to fill this area?
I’ve tried using a dash button, but a WiFi extender stops it from being detected. The Flic button looks good, but they’re quite costly. The Xiaomi set up looks like the best option, but I’m only thinking of a single button for now so a gateway seems excessive.
Edit: could it be possible to use a sonoff rf bridge (flashed) to listen to for rf button press and forward via mqtt? Or does it only work the other direction? That’d be £10 solution for the bridge and remote!
