I've build a solar station with an ESP32 using LoRa module. Even that wasn't much fun as I was forced to keep in light or even deep sleep as often as possible.
An option would be to use a Nordic NRF or STM32WB and use the BLE long range mode.
This submission was a blatant attempt to boost his blog and in turn his product's website; the whole thing looks to me like a scam.
The other items on the blog are clear keyword-of-the-day click-chasing and this is obviously ChatGPT output: https://khalsalabs.com/the-essence-of-paul-graham-essay-on-h...

The other guy has a lot of "look at my expensive stuff" and "the secret to success!" videos (and some videos about using AI to make videos...)
The company's website is a joke. Hilariously bad attempts at SEO in the title, the ad copy is littered with grammar mistakes, and so on. "Best canadian dog tracker"...what?
So the title is wrong/clickbait, the contents smell like AI generated garbage (although shorter than I would assume) and it means very little to anyone
