To be honest, I thought this was something you could just do with HE directly. Like set the values on one device based on the values from something else. But then I could not figure out how to do that. Yup, I would be interested in sub devices.
@snell I don't think you let anyone down. I feel if we all work together we will keep making the idea even more great. I'm not sure how you feel about sharing the code, but maybe we could combine it all into one project or something. We could have some core components which deal with common stuff and then specific areas for Abient and/or Ecowitt and some of the other offshoots (like Metrobridge) etc.
I think it would make sense to work together rather than have everyone create new drivers... but maybe that's just me.
I'm happy to help as well. I have the devices so I can test, but I also know how to code so I'm willing to jump in there as well.
