Current Sensing?
-
Would be great if someone could design a mysensors open hardware board for reading the power meter blinks. One that could be mounted on the meter directly.
-
When googling images of residential power meters they don't look that different to each other. The biggest difference is if they're squarish or round.
It might be hard to mount the full sensor with batteries on all types without hiding the digital display. So maybe the "eye" must be on a optionally brake away child board.

I will take a look at this once i have my AC double relay with switches sorted. Talking of such, would someone like to take a look at my code to see if i have written any issues in there?
Don't rely on me getting this made quickly though, too many projects on the go at the moment, but it sure is on the list to do!
I will start doing some research into the different types of boxes. It maybe a case of just making different enclosure designs to be 3D Printed for this module. Maybe a daught-board config like you're suggesting too @hek.

i've already thought about designing some power monitoring stuff, but i saw there are already nice opensource hw at emon, and didn't want to reinvent the wheel..
for instance : https://shop.openenergymonitor.com/
the arduino shield is pretty cheap imho, can be mysensorized as it's rfm69 compatible, or not so hard for nrf as it's a shield
there's also an optical meter connect it to your favorite node, sensebenber or others homemade, you should be almost done ;) -

I've now just realise how easy this module could potentially be. I also don't like the idea of it costing nearly £20 for that sensor that sticks onto the LED. If we want a dumb node option, this sensor on the front relaying back to MySensors like the example sketch does right now, but i'm thinking a sensor like that small round module that sticks onto the meter, connected to the arduino (possibly through a 3.5mm jack to make it simple for remove and install) and then a custom made atmega board in a box sending off the data to MySensors.
I think i may have my next project already! I may make this nRF24l01 and RFM69 compatible rather than just the nRF24l01 that i use. We could get this stuck on the front with some simple velcro tape cut in the same shape as the light sensor module to be neat, a little 3D printed case with another custom made board holding the light sensor circuitry inside.
I'm going to draft up some ideas for this and publish here for you guys to see.

@Samuel235
cool. i remember that i saw a cheaper one, but i can't find where, will try to recover mem..
in France, we have the blinkled too, but we have sort of serial protocol on power meters for getting multiple infos. -

I would like to make it a complete product to then possibly hand over to the team here to then sell on the store for themselves or to put it on the build page as a nice, complete product like the sensebender or such.
What are your views on DIN Rail mounting things, do many people on MySensors do it do you think, is it something that you like the look of and would contemplate doing in your electric cupboard? I don't do it simply due to location of the electricity cupboard in my house, not really possible for myself.
-
oki, keep the good work ;)
i know in France people prefer DIN rails mounting. makes sense, but can be done in lot of ways.. -
Slightly off subject, and lets drop back onto subject after this question:
Would you guys welcome a gateway enclosure that is modelled to fit onto a DIN RAIL? I might come up with some models for the different arduino setups for the gateways that people are running and create a few 3d printable models to put onto the build page too....
-
maybe useful for some people. but i wouldn't put my gw at this place imho..

Openenergymonity seem to resell "BBSP-LPD" by enistic.
http://www.enistic.com/homepage?start=10@hek said in Current Sensing?:
BBSP-LPD
Do you have a link for the product on Openevergymonity? Can't find the product you're speaking of.

@hek - Do you think there would be a specific need for a clamp sensor over a LED sensor node? Do you possibly think that people would be clamping individual lines out of their fuse box rather than just wanting to know what the overall usage is?

maybe ot, but for the fun, someone selling iot devices for the electric cupboard, told me once, he had to have an expensive decennial insurance for selling his devices even if it's only connected to the serial protocol and his device is dc.. crazy! hopefully we know what we do :)
