Hello. I found this forum on Google. I hope someone can give me some tips on where to start.
I am not an engineer or even a hobbiest in this area. Just a guy wanting to do a specific thing.
My home has an AMR (automatic meter reading) water meter. It broadcasts its serial number, meter reading, and some other data via its RF transmitter so that the utility can drive by and read it monthly without having to get out of the vehicle. In the interest of monitoring and lowering my water usage (we live in a semi-desert area), I would like to make use of that data in (more-or-less) real time. For example, to monitor for leaks without discovering it on my bill 4-8 months later.
This is the water meter: **broken link removed**)R900i/Product%20Sheet_EN.pdf
It says it uses 910 to 920 Mhz spread spectrum.
I found AMR modules from china that specify this:
I don't really know how spread spectrum works... so does the fact the receiver operates at 915mhz, and the transmitter has a range with 915 exactly in the middle mean these should be compatible?
Or am I on the wrong track. Is what I want to do possible? If so, how might I go about it? Thanks.

I found AMR modules from china that specify this:
Carrier frequency: 433mhz, options of 868/915mhz;
