ESP inside!

[Fettkeewl]

Hey @bj00rn

Did you notice that it's an ESP inside the LOKE-01?
Shows up as espressif in my router like all my esps 😋

Have you checked the hardware or are you a software only kinda guy 😄

Hi,
I noticed when I first got the machine too, and then researched elaborate ways to mod it to pull the data. I found a post for a similar machine with a how to guide. Luckily, I stumbled upon bj00rn's integration, which was a god send :) 👍

Software :-) mostly. I noted it shows up as espressif too when I was looking at ways to implement autodiscovery. Came up short here since OUI/MAC seem to be generic esp stuff and the hostname is generic too.

If we could only get the schematics :P and throw in Tasmota /ESPHome

That would be an interesting project for sure but it lies out of scope for this integration.

@Fettkeewl @bindingofman what is the last :XX byte of your mac adress? Maybe (not likely though) they are hardcoded somewhere and we can use it for autodiscovery. Mine is :b2

I'm not to fond of how the saleryd handles heating and how it can bring down the RPM of the rotor.
I'm trying to remedy this through an automation.

Care to give your take on the code?

Basically if rotor spins down and stays down I increase the wanted temp (18°)
If the heater heats more than 30% I decrease the wanted temp (15°)
If the temperature outside is above my treshold I use my calculated flows (home mode, 80%/80%)
If the temperature outside is below, i drop the flow a bit and make sure I have alittle more extract air (away mode, (60%/65%)

I think if you enable cooling mode it will force rotor to 100% regardless of temperature. Oddly enough cooling mode does not seem to disable EVE as the name would imply. Enabling fireplace mode and letting the timer run out will also force rotor to 100% for 24h.

Other logic looks fine from the looks of it. Im no HA automation expert though :-).
