Add support for RainPoint - High Precision Rain Sensor Model HCS012ARF

[effort10]

Good Day,

I am new to this and was wondering if someone could please assist me in extracting the rainfall data from the below device.

All i have done is run rtl_433 -A and i get the below dump. Please let me know what else i need to execute to get more details.

Hi,

I have supplied some more info by removing batteries and then putting batteries back in and capturing the first code and then manually tipping the bucket and then capturing the code again once it gets sent. i did this 10 times. Hope this helps somehow

It seems to send 10 codes each time, 9 of which are the same but the 10th one is different.
Below are the results.

Tipping code (duplicated 9 times),tip number, 10th code (could be battery or other info)

{67}a6f87fbdd7ffffef6 - 0 tip (On inserting batteries) , {66}a6f87fbdd7ffffef4
{67}a6f87fbfebf7ffef6 - 1 tip, {66}a6f87fbfebf7ffef4
{67}a6f87fbfebfbfffd6 - 2 tip, {66}a6f87fbfebfbfffd4
{66}a6f87fbfebf7ffeac - 3 tip, {65}a6f87fbfebf7ffea8
{66}a6f87fbfebfdfff2c - 4 tip, {65}a6f87fbfebfdfff28
{65}a6f87fbfebf3ffd58 - 5 tip, {64}a6f87fbfebf3ffd5
{67}a6f87fbfebfbfffb6 - 6 tip, {66}a6f87fbfebfbfffb4
{66}a6f87fbfebf7ffe6c - 7 tip, {65}a6f87fbfebf7ffe68
{67}a6f87fbfebfefff76 - 8 tip, {66}a6f87fbfebfefff74
{66}a6f87fbfebf5ffdec - 9 tip, {65}a6f87fbfebf5ffde8
{66}a6f87fbfebf9fffcc - 10 tip, {65}a6f87fbfebf9fffc8

Thank you
