Zigbee gas detector for kitchen

Toasty · January 21, 2017, 8:23am

Just got mine late this week, seems a more elegant version than the original one I have. Hopefully will get it installed soon

@jrhbcn Yea man! Life saver!! Thanks for the work!!

I’m thinking about buying this to add since we have LP for our stove and water heater.

Any be kind enough to write up a guide on how to get it working?

Just bought this on Amazon.

Smart Combustible Gas Sensor https://www.amazon.com/dp/B01G4QP0QC/ref=cm_sw_r_cp_api_J5OPybB5FGY6K

@jrhbcn I hope your code will work for this!!!

The link does not seem to be working…can you point me to where the code is?
Thanks!

Looks like he might have reorganized his GitHub. The code is still there.

Yes thanks @SteveWhite. I re-organized it so now GitHub integration should work in smart things.

vilayanur · February 17, 2017, 5:26pm

Thanks so much!

Brad_Langhorst · February 17, 2017, 6:37pm

I’m debating buying one of these for my garage, where the gas furnace and water heater are located. Are you guys pleased with them?

blebson · February 17, 2017, 6:39pm

It looks like the sensor you listed only works with that companies zigbee module, not with any other system.

vilayanur · February 17, 2017, 6:46pm

Thanks Ben, Ive repurposed IRIS before for ST, I am hoping that the new device handler by @jrhbcn should be able to control this? Not sure, but will try.

blebson · February 17, 2017, 6:50pm

The issue is that the device doesn’t seem to be Zigbee HA 1.2 compatible. Zigbee has many different profiles but SmartThings can only speak to Zigbee HA devices.

vilayanur · February 18, 2017, 6:35pm

Thanks…from the pictures it seemed like the Homi device and this were identical. Don’t know why the internals would be different. But good to note. Ill check when it comes in.

JDRoberts · February 18, 2017, 8:22pm

There are many devices that use the same external casing but have different radios inside. For example, you can get a Schlage lock with either a zigbee radio module or a zwave radio module. So that’s quite common. You can never go just by how it looks on the outside.

Zigbee is even more complicated because of the use of multiple profiles.

FAQ: Zigbee Application Profiles, or why not all zigbee devices work with SmartThings FAQ

Zigbee is always zigbee, but the standard allows for different "profiles,"including manufacturer proprietary ones. [image] These are not all able to communicate with each other, they don’t even use the same addressing schemes. SmartThings uses the Zigbee Home Automation profile (ZHA 1.2) and part of the Zigbee 3.0 profile. Devices using other zigbee profiles may be able to join to the network, but their communications may not be understood, or they may frequently drop off because they don’t receive a handshake message they are expecting. There a lot of different ways to explain this, but I think one of the easiest is to think of zigbee as a post office and the different profiles as different languages. The outside envelope for different messages may look similar, have a specific format…

Many manufacturers choose to use a proprietary profile so that they can add features or security encryption which is not in the base standard. For example, in the US it is quite common to see zigbee sensors sold in two versions, one for control 4 and one for ZHA , where the only difference is the encryption used.

@JDRoberts, @blebson,
Thanks for the discussion. I received this yesterday. Just as an FYI Smartthings picked it up just fine with the device handler. I even tested it. @jrhbcn your code worked for this. I still need to update it to say gas instead of smoke ( i think the earlier code is the version i have) Here is a snapshot…

Thanks all!

blebson · February 19, 2017, 7:58pm

Great find then, be sure to answer the question on the amazon page asking if it works with SmartThings!

Brad_Langhorst · February 20, 2017, 6:45pm

Darn it - out of stock on Amazon. I’d really like one of these in my garage to monitor the gas lines.

EU plug but 100v so all you need is cheap adapter

@Brad_Langhorst,
It seems aliexpress is carrying the USA plug type now. Ping them

inpier · March 13, 2017, 2:28pm

Just received mine from AliExpress and have it working with the above DTH.
So thanks @jrhbcn

Installation was easy.

Installed Device Handler
Plugged Gas detctor in to mains outlet. It started cycling the front LED green - yellow - red
Went to SmartThings App and ‘Add a Thing’ and it found it straight away. Homi Gas Detector.
The front LED was still cycling green - yellow - red so I used the Pin provided in the box and pressed the Network Hole on the side for 3 seconds and the LED stopped cycling and stayed Green.

I then prressed the Test Button on the Unit and the Alarm sounded and SmartThings reacted correctly.
