I bought a new flood detector the other day and forgot that I had to change some Z wave settings to make it report correctly on my other one. Then there are other devices like Monoprice PIR sensors that require a template binary sensor to work correctly, Z wave smoke/CO alarms that require a template binary sensor to work correctly, etc. etc.
I was thinking, maybe we need a device wiki on the Home Assistant site. Then anyone could come in and search for their device, whether Z wave, Zigbee, wifi, whatever, and get all the instructions they need to make it work as well as user-generated templates and other configuration files. It could even include instructions on how to pair correctly (think locks and secure devices), factory reset, etc.
How hard would it be to add this feature and allow for users to contribute to it? I know nothing about web development, but would definitely contribute content.
