Dipping my toes into #HomeAutomation starting with a couple of #Sonoff temp/humidity sensors + Dongle Lite to use with my laptop and #HomeAssistant before having a dedicated hub.

That's £51 so ok to play and get the basics.

Got any thoughts or suggestions?

Home Assistant Green looks good for a dedicated hub but at £150 a bit much until I've tested the basics out. This is for a house I'm not living in yet so monitoring is all I need.

If the above goes well and I add a dedicated hub I'll probably use an old mobile with cheap broadband plan as a hotspot to allow remote access as I don't have broadband.

Does #HomeAssistant help handle IP address changes by the mobile ISP?

I have in the past hacked my own and could do that again, but wonder if this supported as it must be a common requirement for this kind of setup.

Or wait, do folk use a mobile app over the internet when not at home (with privacy)?

@happyborg low power consumption is important to me, so I can always recommend a raspberry pi 4 or 5 for a start. Upgrading later is pretty easy. For dynamic DNS there are integrations for Duck DNS or Namecheap that you can use. I just recently modernized them, no-ip also exists but is still a legacy integration.

@happyborg There are several options for external access:

- Home Assistant Cloud, from Nabu Casa (easiest, €5/month; you'll also get IIRC 5GB for a machine backup);

- If you have your own domain, you can use something like Cloudflare Tunnels (free, though you need to pay for the domain; medium difficulty);

- If you don't have a domain or don't want to fiddle with it, Tailscale or similar allow you to create a VPN network only accessible to machines on your account (free, easy to medium difficulty).

@happyborg I just use an old R Pi (booting off a decent quality USB stick as ever so slightly less prone to corruption than SD cards) and run Tailscale for remote access - easier now there's an integration to install/manage it within HA
@schmerg thanks. What kind of things do you use HA for?
@schmerg I got carried away and ordered a refurbished  mini PC.
@happyborg I have small Intel N100 box that I'm planning to move it to Real Soon Now
This sort of thing

@schmerg I hadn't heard of ProxMox until this thread and now I feel the pull of that rabbit hole and can imagine adding multiple mini PCs and whatever keeping me warm in winter.
@happyborg Yeah.. I use Tier1 for sourcing my refurbished Thinkpads and considered a mini PC from them but the N100 was cheaper (tho I do have discount codes for Tier1)

@schmerg I just went to ebay  These things are so cheap anyway. I'll keep Tier1 in mind if I start to fill that room. 🙂
@happyborg A few things on smart plugs with schedules and manual override (coffee machine, heaters in the studio), pulls in weather forecast, tube status, live departures, family calendar & bin schedules, home/out status (by phone presence)
ie mostly a "by the front door status dashboard for when I'm about to head out or just getting home"
@happyborg i would buy a cheap nuc and then you can go all out on hone assistant but also other vm’s if you use proxmox

@mvrenselaar that's interesting thanks. Hadn't heard of either of those.

So your suggesting an #NUC and use #Proxmox to support HA and other handy apps in different VMs? Do you have a setup like this?

@happyborg @mvrenselaar

Of course you can do that. Actually, that is the main point of using #Proxmox

I have a Proxmox here that runs HA, Checkmk on Debian, RHEL and Windows VMs.

Aside: as long as HA means "Home Assistant" and not "High Availabilty". For the latter you need more Proxmox hosts. If one fails, the other one will run the VMs.

@robertdahlem Yes I meant Home Assistant. Thanks 🙂

@mvrenselaar

@happyborg yes. HA in one, pihole in another and whatever i want as well.

A whole new rabbit hole :)

@happyborg Do you have an old PC or mac mini laying around? Maybe even a laptop or macbook? I have my HA on a mini PC with ProxMox.

@happyborg Your first HA machine can be just about anything.

I usually suggest one of those 1L mini PCs that come from enterprises (check out Project TinyMiniMicro). You can get those second hand for under €100 rather easily, they'll be able to be expanded way more than any RPi or other SBC, and since they're technically enterprise gear they're built like tanks.

Hope this helps!
