More 434MHz stuff to look at later

Acurite #0899 self emptying rain gauge – at Amazon

Blog post on reversing the signal from Acurite temperature sensors; may be similar for the rain gauges.  Also mentions the RTL SDR.  Probably wouldn’t be bad to have.

Another blog post regarding reading the Acurite 5n1 station.  Possible that part of this will already cover the rain gauge.  Also discusses SDR and mentions the rtl_433 tool.

This blog post looks like rtl_433 supports the Acurite 896 decode natively, so if the protocol is similar or the same it may be simple.

RTL Software Defined Radio – at Amazon – seems like it’s probably a decent model, some good reviews.  Looks like there’s a little more to it than just “buy this and set up the software”.

Bought a cheap receiver off of eBay from Hong Kong for $7.31 (original listing).

Also, here was an Instructable about making a cheap combination RF/Bluetooth/433 MHz remote using an Arduino.

  • Did this 10-Oct-2018 with an ESP8266-12E, and it worked well in receiving from a Spigen 433MHz doorbell transmitter.  Only minor change was configuring “mySwitch.enableReceive(4)” instead of 0 for use with pin marked D2 on the ESP.  Range was only a few feet with the receiver I was using, though I wonder a bit if using the “ReceiveDemo_advanced” would improve things at all.  Need to play with this more
