Ahh, yep. My lack of specifics certainly isn’t helping anything.
I suppose my intentions were to make a post with more detail, but for now, here’s some important ones:
The 5v/12v refers to the power options of my initial experiment device, which is the eWelink Zigbee 2-channel relay, which has router capability.
It can be powered from 7-32v and 5v via the USB input.
I’m wondering if the Zigbee and RF portion of this device share the same little antenna coil on the board.
Ultimately, I will probably use Zigbee 3.0 mini RGB-CCT controllers, which there are power options for those same voltages.
I’ll post images of the pcb and module/IC when I get a few of those, but here is a link to the devices I’m looking at:
5-24V Zigbee 3.0 DW/CCT/RGB/RGBWW/RGBCCT LED Light Strip Wireless Remote Controller For Tuya Alexa Smartthings
The practical use of these repeater switches/led controllers will be whatever you can imagine a switch or led controller would useful for along a narrow road with a few blind curves… warnings, general illumination etc…
obviously I’m focusing on inexpensive devices and integrating them into solar power solutions.
The router/mesh function of these DC devices are relatively new, and power consumption is reported to be < 1 watt, but I can scale to whatever the requirements will be.
