Great question! The gameplan is to sell what we can for now (to stay in business - we're eating Ramen and Potatoes over here!) and that is Zigbee as there's no shortage of chips at this time (or at least this is what we're told).
We have two manufacturers... A Z-Wave one who has made all of our Red Series products and a Zigbee one which is new who will be making our Blue Series.
The issue we have is our Z-Wave manufacturer either lost allocation or had something happen in that they are struggling to get Z-Wave chips. Our Zigbee manufacturer said they can get us the volumes we need, but of course that would require us to rebuild everything from scratch (tooling costs, engineering fees, and firmware costs).
Our hope is by teaming up with another Z-Wave player that we can bring more volumes to the table to see if that helps the Z-Wave manufacturer better negotiate with the chip supplier. At the same time, we need to explore what the new manufacturer can do and (possibly) work out a deal to where they waive some of the tooling based on volumes.
The good news is that there are experts in our side now and I can focus where I'm good at (my background is marketing/branding... Definitely not supply chain lol).
So, to summarize - short term we are focusing on Blue Series while simultaneously working to get Red Series back in stock be it with our original manufacturer or our new one.
Not sure on what will be 500/700/800 series quite yet.
