I primarily use this to track my 30+ plants using cheaper, lower power, pairing-free and more reliable RF ping-based soil sensors.
I dooo get pager alerts about my potted plants tho.
I acquired a tactical LTE base station on eBay that had a fairly clean copy of Druid Raemis in a VM on it. After some wrangling and reverse engineering, that VM is now the core of my home CBRS LTE network with a license-free band 48 radio in my house. Why? Cordless phones with a second SIM card. ;)
I don’t think this is too gnarly but I ingest 433MHz/MHz RF blasts from the neighborhood using a software-defined radio.

Back when I was a prof., there was a monitor mounted on the wall outside my office whose display I had control of (it was from the previous prof and I inherited it).
I connected it to a RPi and set it to display a website. The website was one that I wrote that did 2 things. First, it displayed a random XKCD comic, rotating every 30 seconds, as well as a scrolling message at the bottom (usually just a disclaimer that the images were chosen at random). Second, it was an endpoint for Twilio.
The end result was that I could send a text message from my phone and it would display that message on the monitor on the wall outside my office. It rejected any message that was not from my number. I used it to display things like: "Had to run across campus. Be back at 1:30." or "Left for the day." And, since people would often stop and read the comics, they would definitely see the message.
> Future project: I have chickens. They lay eggs. I have cameras. I want to know which hen lays how many eggs. Solution? AI image recognition of the hens (who is who) and if they have laid an egg. Any inputs welcome. What happens to the ones that don't lay enough?
Hens are so fun to have around, are often really friendly and playful and keep company to you and the other hens. So you keep them.
I've built (now improving) a fully automated real-time ML stock trader in Rust. It's hosted on-prem via 6 Raspberry Pis using Kubernetes.
I have an ESP32 with a sim card and a relay which is controlling the plug to my router. Should I end up being locked out, while someone else has managed to get in, I can send a specific text to a specific number and the esp will kill the power to the router.
Overkill? Considering no one has ever managed to get in, probably. But it's better to have the option than not.

Are there any reliable, but low cost soil sensors? Most of the ones I've seen are surrounded by complaints of corrosion and premature death.
Have had a bunch of them for 1-2 years and they all look brand new and I haven’t swapped any batt.
I don’t use the hub.
