Sensor Node V2.0

[Tommy Sharp]

Being able to buy something like this that is "all in one" will be great for us newbies! A more accurate temperature sensor would be ideal and worth the extra dollar!

@Tommy-Sharp "all in one" is one of our goal while working on the project boards

Thanks all for ideas. We plan to have several project specific boards.
First one will be the battery operated board designed for wireless sensors.
Bellow is updated picture, should look better now.
Sensor will be the digital one with precision 0.5C or better and very low power consumption

Should we seriously support 5V from battery? For many applications 3.3V are sufficient and it will consume much less power from the battery.

Relays, dimmers, SSRs will be managed by another board.

@axillent How is this project coming along? Looking forward to a standardized PCB version.

@clippermiami we are currently in discussion with possible partners, we discussing production of the PCB and assembled PCB
in parallel I'm doing a prototyping of the battery operated board
Battery operated board will came first, later we plan to release a set of stackable boards ready be used for switching, dimming and integration behind a wall switch

@axillent LOOKING forward to it, a nice PCB makes a good clean project.

North American wall switch?:ballot_box_with_check:

@BulldogLowell from electrical side it is a clear plan to be universal between 110/220V 60/50Hz etc. to support both US and EU standard
from the form factor point of view I have a view to EU standard but not US.. Hopefully we can be universal too but I will need your input on this.
Even I'm not sure what is "North American" stands for :) is it common for US only or for Canada too?

While for battery board the design is almost 95% clear the wall board is still under discussion.
Most likely it will be stackable form factor with universal MCU -board and many different power&switch&dimm sub-boards
All feel free to provide your inputs, to share ideas or wishes.

@axillent North American standard is common to both US and Canada.

[axillent]

@clippermiami what can be the maximum acceptable form factor?

[clippermiami]

@axillent From my recent experience the Jasco/GE switches are about the biggest thing you can got in a North American wall box and even that can be a challenge. Depending on the number of circuits that come into the box and the number of connections (wire nuts, or whatever you use for the connections) can create quite a bit of congestion in the box. It can sometimes be a challenge to fit even the Jasco switch :-)

Basic sensors that you are using for logging and alarm are ok. However, when starting with power/switch/dimm, then security starting to be a big issue. (Also when using the sensors to control something)
I hope this boards will be sold with a big warning on that point.
(I'm not negative to mysensors and using those myself, why would I else be here :). I'm just not a fan of people seeing this as a complete HA solution)
