Watchman Sonic Plus detected as standard Watchman Sonic and no leak flag

[Mail Torent]

Hi,

I have recently bought used diesel tank from late 2015 with Kingspan Watchman Sonic Plus equipped with a float leak sensor. I don't have the receiver.

I can receive it using rtl 433, surprisingly it reports as Oil-SonicSmart (not Plus/Advanced). I am using yesterday master branch, as I noticed there were plenty changes regarding similar sensors lately.

The depth and temperature seems to be correct, the only thing I cannot get is the leak sensor activation. 

The flags is 62 all the time, most of the samples in the repo are 128. My device transmits every 15minutes and 15 seconds, which is also unusual.

Is that flag known to someone? Or is it maybe some different variant of watchman?

Attached is cu8 and some screenshot:

The "Advanced/Plus" was added with https://github.com/merbanan/rtl_433/pull/2323

The "SonicSmart" is really old. https://github.com/merbanan/rtl_433/pull/221 more info in https://github.com/merbanan/rtl_433/issues/218

The protocols are different enough, there is no overlap. Naming in these Watchman/Apollo/... isn't obvious, so your device is really of the "SonicSmart" protocol kind.

So far we only known that the 0x1 bit in flags is rebinding and suspect that 0x8 is leak/theft alarm. No idea what 0x80 (128) is.

OK, thanks for the info.

I suspected that flag 62 might be low battery or leak alarm, as I had plenty of diesel in the outer tank.

But as I took the leak sensor and rotated upside down, flag still remains as 62.

I wil try -vvv with some options, because then I see something like

Maybe something will change here :)
