Looking for a way to possibly intercept a signal from my Sump Pump to it's internet gateway

So my Sump Pump talks to it’s internet gateway over a 900Mhz connection. Basically has information such as the following.

  • Home Power
  • Battery Charge
  • Primary Pump
  • Secondary Pump
  • Water Level
  • Charging System

I was trying to find a way to snoop on the 900mhz signal if possible to just eliminate their poor app, and have it feed into my Home Assistant server.

The Internet Gateway is SKU: AIC-EGW-915, Part Number: U17-2018, FCC Model: AIC-EGW, FCC ID: Y4B-AIC-EGW and I believe it was manufactured by Arrayent.

I was trying to see if there are any components for an ESP that could possibly work for this application?

This is all the gateway though, not sure if it would be better to try to hack the transmitter. (the battery backup unit)

I believe this may be the transmitter

sounds like hard work.
a starting point may be:

I was originally looking at this for their “mighty Mule” impementation but went a different route.

I’ve played around with rtl_433, but not being well studied in the radio world. I’m a bit lost.

From the look of the frequencies it is probably Lora

I assume (since it has a gateway) that this talks to something over the internet, or at the very least to a local application?

Why not snoop the network side?

My Google also found this which seems to expose the attributes that you list for a pump:

it’s going to somewhere in Amazon, over ssl.

You sound like an advert.
