I made the layout you proposed. It is interesting for the needs of a gas meter and electricity meter.
However, I encountered two problems.
- I can not change the unit of measure (I can only close my eyes and pretend I do not see bad units)
- I have six water meters in the garden watering system located next to each other. Six such devices would be difficult to build. It would definitely increase radio traffic. The solution is one device and 1-8 channels as in the case of HB-UNI-Sen-VOLT;)
So I am not happy with the solution that you have proposed because it introduces limitations in applications.
If you do not find time to adopt "HB-UNI-Sen-PULSE" I will be forced to use HM-ES-TX-WM.
