Supported Oregon devices?

[t...@quarendon.net]

It's unclear from the help which Oregon Scientific sensors are supported. Do I assume that they all use the same protocol, and hence I can use a temp sensor, rain gauge, wind gauge etc?

Or is it restricted to only certain specific sensors, in which case which ones? There seem to be different sensors on the Oregon shop that are compatible with different product lines, so I'm guessing that the protocol isn't the same for all?

Thanks for the info.

So I'm not sure if I should hijack this posting or not, but I know of at least one device that is Oregon Scientific-branded but will not be decoded by the current master version of rtl_433: it is the sl109h sensors (providing relative humidity & temperature).
I've managed to figure out how to extract the rh & temp data from the signal, but I'm not precisely certain how to introduce that functionality into rtl_433: it doesn't match the profile of the current oregon_scientific code, so I guess maybe I need to introduce a new device: something like oregon_scientific_sl109h.c ?

Looking around, there are three protocols used by Oregon.

The RFXCOM 433 transceiver specifically mentions it supports Oregon protocols 1, 2 and 3.

The Oregon THGR810 sensor has a little "3.0" logo on it, which putting 2+2 together and making 15 implies "protocol version 3".

The Oregon compatibility list also suggests that THN132N sensor and the THGR810 sensors are not compatible, they share no compatible receivers.

So my believe is that the WMR series products use a different, version 3, protocol. The code in rtl_433 supports protocol version 2, though there is a different device type that supports protocol version 1 (device 49). 

So protocol version 3 would be another device type.

At the moment I've acquired a THN132N on the basis that I know it worked. When I've got more time I may acquire some WMR series sensors and put some effort into decoding those, it would be hard without a head unit to know what the right values are.
