Hi all,
I was wondering if anyone could point me to a guide related to the hardware and steps required to install my home assistant integrations.
I've seen quite a few around but I'm still unclear about which one would be the best solution.
I use Octopus intelligent go at home and ideally I would like to be able to discharge my battery automatically before the off-peak rate kicks in.
Thanks in advance for any suggestion

There’s a couple of schools of thought on the hardware, typically a Raspberry Pi, an Intel based NUC or bare metal on an SFF PC - my preferences are the Rasp Pi or the SFF PC.
A home assistant rapidly takes on more within the house than you expect it to, so I would strongly recommend getting a higher spec than the minimum required to run your applications.
On the Rasp Pi, a Pi4B with 4GB RAM or the newer Pi 5 again with 4GB RAM are good choices - don’t use an SD card, they both boot and run from a USB SSD drive - it doesn’t need much space so a decent 128GB will do the job.
A lot of users go with the small form factor PC which is again an excellent choice, i’ve linked you to Tony’s description on his install as some really good tips there https://github.com/TonyM1958/HA-FoxESS- ... a-USFF-PC
You’ll need to connect to the inverter using an RS485->TCP adaptor - there are lots of good choices, from ethernet based devices to USB RS485 adaptors - this is a link to the wiki for the home assistant integration, it explains the modbus wiring and you’ll see common adaptor choices on the right hand menu https://github.com/nathanmarlor/foxess ... ring-Guide
There is a really good octopus integration that lets you get access to the intelligent api that you’ll find here https://github.com/BottlecapDave/HomeA ... opusEnergy
If you have any questions (i’m sure you will), just fire away.
