PI5 4gb and POE HAT £72 plus a cheap case. Thats all i would need i think. I want it separate from my server or id install it on my NUC but thats running Plex on Windows.
It’s cheaper than the dedicated Green hardware. I just dont want something thats only just fast enough for it and leaves me no upgrade path.

That spec will be more than enough for HA. I’d add a cheap SSD and enclosure to that shopping list as the SD card WILL fail given time. HA records a lot of data, making constant writes to the SD card.
 
That’s precisely my point regarding a PI though, by the time you have added an SSD and enclosure or an NVME hat, because home assistant will eventually burn out an SD card, you are basically at mini PC levels of cost.

Don’t get me wrong the PI will do a fine job, they just aren’t cheap like they used to be and you can get a lot more hardware for your money elsewhere.

Those N100/N150 mini PCs run at like 6w at idle so power consumption is decent also.

So maybe this one would be better, Poe and m.2?

PoE M.2 HAT+ (B) for Raspberry Pi 5

The Waveshare PoE M.2 HAT+ (B) has been designed specifically for the Raspberry Pi 5, integrating Power over Ethernet (PoE) functionality alongside an M.2 interface, enabling use of high-speed NVMe SSDs (sizes 2230, 2242, 2260 and 2280), including support for SSD booting in Gen2 mode (and Gen3...

Yes, definitely IMO. Even if you don’t get an SSD right away, you will eventually because a standard SD card will die.

A high endurance card will last a bit longer but the constant small writes trash them pretty quickly still.

Edit: The SSD doesn’t need to be fast or fancy, I think a PI is only PCIE gen 2 with a single lane so almost any good quality SSD will do.

How much does it write to wear them out?
 
It depends what you use it for.

Most common applications require constant logging data points and that’s not something you’ll want to store in ram because you’ll need to protect it from data loss.

Zigbee is the wireless standard, ZHA or Z2M (Zigbee2MQTT) is how Home Assistant comunicates with the devices.

ZHA is built in to HA, so it's easier to get started.
Z2M supports more devices, but you need to setup a MQTT broker (normally Mosquitto).

This is a good explanation.

For now I just need ZigBee bulbs and sensors mostly Hue ones, Unifi cameras and lights.
Got a few WiFi plugs as well.
 
Got my first Philips hue light strip set up, set a timer in the hue app.
The hue app seems to do everything I need, is there any advantage to using the Apple home app, does it do anything better?
 
Quick Q - I’m going to set up HA to use Predbat for my solar setup. I’ve seen Ethernet to RS485 and USB to RS485 adapters. The advantage of USB is you don’t need a separate power supply, but is there any downside to them?
 
Wanted to understand water usage on various appliances and the household in general now that bills are +45%.. used the below project and its working perfectly with my Itron Aquadis+

Getting nice real time readings as well as meter totals and daily totals. Also integrates into the energy section so you can more easily put a number to each hour period in a day for consumption. All in less than £10 in parts and a little assembly.
