Home assistant / MQTT showing plato not SG

[liams1989]

Hi, I'm wondering if I'm doing something wrong.
In home assistant it's showing °P but the payload appears to look like an SG reading?

Double check the gravity calculation.

Typically I use this for SG:
(1.0000E-6*(tilt^3))+(-1.3137E-4*(tilt^2))+(6.9680E-3*tilt)+(9.0704E-1)
I believe the Plato equivalent would be:
(2.3351E-4*(tilt^3))+(-3.1541E-2*(tilt^2))+(1.7133E0*tilt)+(-2.3081E1)

I'll give both of the formulas a go and see what the MQTT output is. Thanks

Nope. The MQTT is still:

Payload
unit_of_measurement: •P

And as far as I can see it cannot be changed when using MQTT
