Get state of physical inputs on a heat pump

[masterx1981]

Hi!
I have a Buderus WPLS 8.2 (recognized by ems esp as a Enviline, Compress 6000AW/...) , equipped with an HMC310 controller (recognized by ems esp as an RC300/RC310/...).
I'm trying to get the logic state of the inputs. Today i've played a bit with the bus, and i've discovered that when no inputs are inverted (i have available only i1 and i4) i get:
HpPower(0x048D), data: 41 00 10 08 14 00 00 00 00 00 00 00 00
If i close to gnd i1 i get:
HpPower(0x048D), data: 41 10 10 08 14 00 00 00 00 00 00 00 00
If i close i4 i get:
HpPower(0x048D), data: 41 80 10 08 14 00 00 00 00 00 00 00 00
If i close both i get:
HpPower(0x048D), data: 41 90 10 08 14 00 00 00 00 00 00 00 00

If i invert the logic of i1 (without anything closed), i get:
HpPower(0x048D), data: 41 10 10 08 14 00 00 00 00 00 00 00 00
While if i invert the logic of i4 i get:
HpPower(0x048D), data: 41 80 10 08 14 00 00 00 00 00 00 00 00

So for know the REAL state of the inputs, the information of that byte must be integrated with the info on the hpinNopt...

Now i use it as a custom entity on ha, but would be nice to have it as a string interpreted as "bit array" (like the hpinNopt).

Thanks!

Can you give some examples of what the string would like look? Also a nice name, and then we can code it.

From yesterday i've not seen any other value than what already discovered. My heat pump have available only i1 and i4 (i1 is connected to an on-off thermostat, and i4 for now is disconnected), but seem that some heatpump out there have available i1, i2, i3 and i4. I suspect that also the other input states are in that message/offset.
For not have an mqtt sensor for every one of them, i was thinking to create something like this (obviously read only):

But if you consider that have a separate entity for every input is ok, the result will be the same...
For the name, hpinstate - input state (in case of single "array") or hpin1state/hpin4state-input 1 state/input 4 state (in case of separated entities) would be ok?
Thanks!

Ok, we'll need @MichaelDvP's brilliant mind to come up with the bit format

I've added the input x state entities to dev8, next PR.
@masterx1981 good catch.

As soon as i have some spare time i'll try it. Really thanks!
