I was hoping to find more devices around me which use 433. Apparently my neighbors don't have any 433MHz devices.

- EvanAnderson 1y agoI'm spoiled. One of my receivers is on a second story and has great line-of-sight to a bunch of houses and a parking lot (where I assume I get a lot of my TPMS "hits").
- fullstop 1y agoI was able to read some data from my electric meter, but the good stuff is encrypted. What I was _really_ hoping to read was my water meter. It transmits so infrequently, though, so it's hard get much of anything or even know if you're successfully receiving something more than noise.
- avh02 1y agoI've been going down this rabbit hole, there are two alternative options if you're looking for a side project, 1 is "ai on the edge" (Google it it's a pretty cool project), which is basically an esp32 + camera that takes a photo of your meter on a regular basis and OCRs the data, option 2 is (and I'll be trying this this week) to get a magnetometer hooked up to an esp32 to read the little magnetic pulses the impeller (in my case) makes (which is how the meter hardware they have reads it anyway), can have calibration difficulties but will be so cheap, there are also existing esphome projects for this.
- fullstop 1y agoThey replaced my older style meter, the kind that you have, with a Sensus Iperl. https://www.xylem.com/en-us/products--services/metrology-equipment-for-utilities/meters/iperl-plus-north-america-water-meters/ https://www.xylem.com/en-us/products--services/metrology-equ... I know that it has a radio, but it might only transmit when it receives a signal from a vehicle driving down the street.
- avh02 1y agoOh, wow, didn't know that tech existed, and no display either? Both my suggestions don't work then i guess : -(
