I am looking to add in Homey a natural gas leak detector and I see there are not many options supported by Homey (even some of the few supported options I see seems not to be for natural gas) and for those I see supported (eg. Shelly Wifi based which is not what I would like as for security reasons I prefer not to add wifi devices to my local network) there is a plug incorporated in the device and not a cable. This is a bit annoying since I think natural gas is very light so the right place to locate it is near the ceiling (maybe around 1 m below) while plugs at home are closed to the bottom of the rooms.
Any experience on this? Thank you for your help.
