4-in1- Soil Moisture Meter Decode

[Sean Scott]

I am a noob to RTL_433 and I am trying to probably do way too much with my limited knowledge but i would like to be able to add these, https://www.amazon.com/dp/B0D22J32NB, moisture meters to my Home Assistant instance.

I have attached a log that i tried to use to decode the pulses. Can anyone help?

Here is the config I am using. I removed the IP, Username and PW

# SDR parameters

device 0

# Disable all default decoders
protocol 0

# Custom decoder based on your signal data
protocol -X "n=DrMeter_Moisture,m=OOK_PWM,s=480,l=1450,r=3800,g=1500,bits>=64,bits<=72,match=55aa,get=ID:@0:24,get=Status:@24:8,get=Data:@32:32"
