Model is AE090JXYDEH/EU, chat gpt has changed its mind about 15 times in a 10 minute chat and is taking most of its info from here ! so if someone could steer me in the right direction id appreciate it, thanks all.
What do you want from the integration? Monitoring only, write and control permission, etc.
@pantherale0’s integration does an excellent job for me. It can write and control as well as monitor. Search this site for references and reviews (e.g. @pantherale0 and Samsung, e.g.Samsung Gen 7 Modbus monitoring - #8 by pantherale0 ).
monitoring and control ideally, but id settle for monitoring, id love to be able to remotely switch DHW that said!
what hardware would i need here sarah or what thread explains all that?
@Niall_C the hardware is straightforward, but I found the software to be quite complex.
First, I should emphasise that my experience is with setting up HA to drive an HTQ series HP, not a Gen5, so the integration may not work for you.
My hardware is just an RS485-to-ethernet adapter connected to F1/F2 at one end and my broadband router at the other.
Initially I just used SNET on my laptop, via a virtual COM port, but as @pantherale0 explained to me, HA required a VM to be installed. I only accessed HA from my laptop - I never got round to installing an RPi.
@pantherale0 held my hand a lot with setting up the VM and then HA via a very long PM exchange. If you aren’t familiar with VMs, I don’t think that there’s anything stopping me from making this PM public (apart from my shame at having to ask so many naive questions of him), so let me know whether you 1) use SNET (which does most things that HA can do except scheduling), and 2) which VM you have (if any).
I’ve been very busy integrating all the things of my house over the past few months so have been a bit quiet here.
Something to add, Nabu Casa (Home Assistant’s commercial partner) will be releasing new hardware in the not so distant future that might make the hardware side of things easier. Nothing has been announced formally yet.
For Home Assistant itself, Raspberry Pi, cheap mini PC from eBay or Facebook marketplace will suffice - I’ll plug their own hardware here Home Assistant Green - Home Assistant as it just works out of the box.
Happy for you to share anything you think is useful @SarahH I did re-write the VirtualBox documentation a while ago after our chats 
Thanks, @pantherale0, you continue to amaze me…
@Niall_C I have made public my PM with Jordan (@pantherale0), and it’s now appended to the Recommendations for running a Samsung 6th Gen with Octopus thread, starting at around post #60, though depending upon where you are starting from, the whole thread may be worth a quick read.
Thank you both so much I have some reading to do !
Agree with @pantherale0 home assistant works out of the box on a RaspberryPi with zero setup required. Just download the prebuilt HassOS onto an SD card. Or if you don’t have a Pi, the HomeAssistant Green hardware is even easier since in pre-installed. Running it in a VM is quite a convoluted way to run HA.
Agreed, but the VM approach costs nothing (apart from your time…). Not everyone can justify £100 for a RPi or £160 for a HAGreen based on running cost payback. At least that’s the viewpoint of my financial adviser (aka my partner) 
…
That’s true. But given HA needs to be running 24/7 the lower electrcity running costs do make sense to use didicated embedded hardware e.g a Raspberry Pi costs about £14/yr to run 24/7, while a laptop would cost £70/yr or a dekstop PC £240/yr.
Hi all, just wanted to revisit this and also thank @pantherale0 and @SarahH for their advice and input. I have a samsung joule gen 5 system with a 9kw machine. I am a big fan of home assistant and for years i envied everyone else with newer set ups and proper home assistant integration but i found it all a bit daunting. Turns out nowadays given a lot of work by various people @pantherale0 included its pretty easy.
Hardware i bought was an atom m5 stack - Amazon.ie
and paired it with this RS485 convertor which i had to order from ali as i couldnt source locally https://www.aliexpress.com/item/1005003297531645.html?spm=a2g0o.order_list.order_list_main.10.315218026pOLlb
The worst part was waiting on that to deliver. Then all i needed was some cat 6 cable which i stripped and took the strands out from and connected the device to the V1 and V2 and F1 and F2 screws on my control board (which for my unit is in my hotpress with the cylinder rather than on the ASHP itself). The atom connects to my network wirelessly and once i flashed it with this yaml i was good to go.

Then i loaded this integration GitHub - pantherale0/ha-samsungehs · GitHub created by @pantherale0 and i could see lots of data about my system immediately.
For my device i was missing some of the parameters of interest to (water law for rads for example and a few other bits) but with the help of chatgpt i was able to add them in via messing with a few files from the integration.
Dash needs work but currently looking at this to set up optimisation with an AI helper that i need to code in!
One thing i have noticed and i am not sure if its a limitation of my system or if its a change i need to make to the integration but i do not get any data re flow rate, power consumed or thermal output which will make COP tricky! if anyone knows any more on this let me know!
So just a note to say thanks and maybe some of the above is of assistance to other users searching in future.
I’d never recommend a Pi for HA. The disk writes will kill an SD card in no time, I’d suggest.
Got an old laptop? Install ProxmoxVE (PVE) and install HA OS on it.
Depends what else you run on the Laptop, but I think that is too high. My PVE laptop (with SSD) draws about 15W so ~130kWh. £25 PA at my average Agile price of 18p/kWh. I have 5 or so VMs running on that - if each of them was a Pi (as they were) the cost of the laptop is way lower.
I do have a smart switch on my PVE setup (to cycle the laptop battery), but it is only a switch and no power monitoring unfortunately.
The big advantage of the laptop is the inbuilt UPS.
I’m still on the wonderful ‘HA Blue’ for my HA install 
I will have another look at the message IDs, might be that it is missing some for gen 5 or it needs to be actively polled.
thanks a lot, if i figure it out in the meantime i will post back
Industrial SD cards a very robust, I’ve had HA running for 4 years on a Pi SD card without any issues. That said, I do run my own HA on a Pi with a SSD hat for faster access. For a new user who just wants to give HA a try it’s difficult to beat the simplicity of a Pi. I should have been more specific about the industrial SD card requirement.
