It’s Initrode now.

And, yeah, when I tell people I work in tech the response is either “cool” or questions about what we do and how we do it, from the more geeky people. But I also don’t work for a company that “shortens the kill chain” or “connects the supply chain to the kill chain”

EDIT : I want to be very clear that “Connecting the Supply Chain to the Kill Chain” is the real actual title of one of their advertising docs on their official website linked above.

If it helps for comparison, my esp32 got about 2.5 days on a 2,000mAh battery. My nrf52 gets about 10 days on the same battery.

Edit: that was with no charging at all, just “plug it in and see how long it lasts”

I breezed through the other replies and didn’t see anyone asking why you want wifi.

If you’re going to hang a node somewhere and have it solar powered, the nRF52 will give you waaaaaaaaay longer life and easier (solar) recharging. I’ve got nodes that have been out (unmaintained) for three or four years now, running on a 2,000mAh battery and 2x crappy 60mA@5v solar cells, and they’ve never dropped out as far as I can tell… even in deep winter when you shouldn’t be charging lithium-ion battery packs in sub freezing temps : )

I’m probably dumb, but I don’t see why anyone wants wifi from a LoRa node when all it does is rob power/longevity without adding any benefit that I can think of.

You’re telling me I have to climb on top of that building at night, surreptitiously, AGAIN?

Since you covered the important bits, I’d add :

ESP32 if you want WiFi but short battery life, nRF52 if you want long battery life but no WiFi.
