Receiving RF from Acurite temperature sensors

Post by m207365 » Sun Feb 14, 2021 9:21 pm

Recently I started using one of my SDR-RTLs to receive temperature and humidity from Acurite 06002/592TXR remote sensors. These are designed to be used with a matching Acurite base station, which I lost in one of my moves.

The sensors use a proprietary 433MHz protocol, but the rtl_433 software package is able to decode it. I also use rtl_433 to write the data to a csv file. I wrote a Python program to parse the csv file and post the data to a web page. I'm doing all this on a Raspberry Pi, but I originally developed it on a Windows 10 machine.

A crop of the web page should be attached to this post. Nothing fancy, just a simple text web page.

I'm using another SDR-RTL to capture the 915MHz signal from my electric meter. That also uses the rtl_433. Nothing fancy there either. I'm just logging my meter reading every 60 seconds or so. The transmitted meter reading has a .1 and .01 digit giving it 100 times more resolution (10 watts) than the LCD reading on the meter itself.

I might add that rtl_433 is also able to decode my Honeywell security system 344.975MHz sensors, all 20 of them. It was interesting to monitor them for a while, see their heartbeats, etc., but I haven't done much else with those. My security system panel already does everything I want.

Now running everything, except electric meter acquisition, on a Raspberry Pi Model 4. That includes (3) Python programs, as well as rtl_433, influxDB, and Grafana.

One of the Python programs gathers data from my homebrew weather station. Another handles my oil furnace data. The 3rd gathers data from my (5) Acurite sensors.

Still looking for a meaningful way to display some things on Grafana that don't happen very often, like daily oil consumption, yesterday's HDD, etc.

Will probably have to have a separate dashboard for my weather station. It sends in 16 data elements.

Thought you might get a laugh out of my "breadboard" setup :)
