Suggestions to new hardware!

Hello all, ever considered creating a small, affordable, device with only one sensor for example? Like a mini emontx! Intended to be used locally on small devices, for example to use on a heater! I seen how to create my own devices but a official product would be most welcome! Thank you all for your work and time! Best regards
