sure it was fun to make, I mean when you design your devices you can choose the best parts, try to get the best perf.., even if it's a bit more expensive than a very cheap commercial product, in the end, you know what you put in.
If I remember it cost me 15-20$ when I assembled it, not that expensive, vs versatility, sensors, and possibility to change fw.
It's a quite old project, I wouldn't really advise to use 328p nowadays, it could be limited in future, says if mysensors someday get more advanced features, who knows.. it's really just my opinion. Still, I understand it's maybe easier to get started with it.
I made more modern projects, but miss time for release etc
No, I'm still not selling anything. No enough time for the moment. I think it wouldn't be worth my time. Same about compete with commercial products, like a topchef or a craftsman, I prefer to focus on other aspects when designing (quality, verstatility, perf).
If your HA is cost driven, then maybe you're right to go for Aquara. Imho diy for sensors like you mentioned will often cost the same or more than the cheapest commercial products, vs time&learning curve, parts&tools in diy.
Are these commercial products as low power, better range etc as a good care diy device, not sure.. But like I said "premium" has a cost. Pros and cons.
I think for the moment, you can't compare the range of rfm69 module vs 2.4ghz aquara. afaik aqara/zigbee needs more repeaters.
