ic package and power consumption
-
Size matters ?
My question is about one specific point : does a bigger package consume more power ?
I am in the process of replicating a solar/battery circuit and adapting it to my needs (and mysensors of course).
I won't be able to solder tiny SMDs... so i chose bigger SMDs and even through-hole components (mainly resistors and transistors).
Will selecting the exact same component but in a bigger package affect overall power consumtion ?
Or are internal bits dimensioned identical ?
Thanks a lot

No, but usually it can dissipate more heat and so it can be rated for more current if it's a power component.

I am curious about your project. What is it that you're doing?
After several years of procrastinating, I realized that I wasn't going to build my own battery storage.
I ended up having an Enphase battery installed. Enphase, because they had a combiner (solar, battery, grid, and generator) that made sense and a "collar" (a switch that goes between the meter and panel). They system can go off-grid easily.
The downside is that I have to go through the Enphase servers to get my data.

@OldSurferDude sorry i got you in the wrong direction !
I am just building my own alarm unit for home protection. I bought a unit from aliX and salvaged enclosure, solar pannel and a few components (LEDs, piezzo, ...). I am no finalizing the PCB.
Back to your project : please share your knowledge as i am in deep thinking about an off-grid capable solar system. It would make sense to have capability for external inputs such as ethanol-powered generator and wind turbine on top of solar panels. I also want a fairly big battery pack (for peace of mind and also to preserve it from deep discharge).
Can't you find any serial-data connector somewhere on your power panel ?

Glad you clarified the scope of your project. Small scale solar projects are much easier. One of my projects is a "battery powered soil moisture sensor, battery recharged by a solar panel" I use a tp4056 board to charge the battery from a 1W solar panel My Arduino Nano wakes up every hour to sample the moisture report the current moisture level. Corrosion is problematic.
My house battery project is really outside the scope of MySensors, I'll send that in a chat
