It would be nice to have a board dedicated to selling/buying home-assistant related hardware.
Who’s in? Moderators?
I have floated the idea before and the answer is no. We don’t want the legal or administrative hassle.
Advertising your items for sale elsewhere (Tindie, etsy, eBay, etc…) and posting the sale link here however is ok.
Sounds good! Thanks 
Where would be more appropriate to post?
In this category.
Note: this is not meant as authorisation for commercial spam.
Small hobby enterprises and offloading unwanted second hand home automation related items only. e.g.
Tom_L’s second hand unwanted automation device ebay sale 
Tubes Zigbee routers and coordinators
Tom_L’s bric-a-brac garage sale 
smartguys.com.au
Totally agree with these rules.
I meant in the Social Category as a new topic, not this topic.
Sorry. Will fix.
