I feel like this is going to be a deciding factor in how comfortable countries are in the third quarter of the 21st century. "Did they start to get their renewable shit in order by 2025?"

Maybe I'm just a datahoarder, but for me the really obscure stuff is the most worth keeping originals of.

HA compatible Z-wave controller?

Jump

GreatAlbatross @feddit.uk 16h ago

To be honest, part of the reason I leaned towards having the radios on the same box, was simplicity. I have a box, with a VM, VM is backed up, new box could be stood up if needed and restored from a backup. The other was, when I knock over the network (don't ask...), I don't lose logged data from the various sensors.

If you did want to be able to fail over quickly, so long as you make the USB device paths match (ie, have them on the same device in proxmox), you should be able to swap things over inside 10 minutes.

Jump

GreatAlbatross @feddit.uk 20h ago

Is there a particular reason you want to put your z-wave controller on the network, rather than just plugging it into the proxmox hardware? (Assuming I've read your post correctly). Are you looking to do high availability on the VM or something?

I found running HAOS in a VM, and passing through USB devices worked really well, and I just bought the bog-standard z-wave dongle from Aeotec.

Coastal road swept away into the sea in Devon

Plus, the terrain near the coast here is an absolute bastard for point-to-point roads. You'd struggle to make the alternative road any more efficient than the existing b-roads.

xkcd #3196: Aurora Coolness

Jump

GreatAlbatross @feddit.uk 4w ago

Very accurate. When we had the northern lights here, we pulled over on the way to the dark-sky location, and the aurora filled the sky. After it died back a bit, we drove on to the dark-sky, where we spent 3 hours sitting in the dark working out if the green bits were going to spike up again.

Why the NHS still wastes billions on patients who shouldn't be in hospital

Jump

GreatAlbatross @feddit.uk 1mo ago

The 2010s gutting of social services also contributed to this. Services that might have helped the elderly continue to live in their own homes, or supported in their community, got ripped up. So everything slides until they hit the one thing that can't be cut, a hospital bed.

Boiling lobsters alive to be banned in UK animal cruelty crackdown

GreatAlbatross @feddit.uk 2mo ago

I reckon culture-grown meat will be the big one that shifts people away from slaughter meat.

Sure, growing it from a culture will still have people refusing on ethics grounds, but it's damned sight less suffering.

That was the conclusion I reached a little while ago. So I've just stopped eating shellfish as a result.

I'm now trying to reduce the amount of cow I eat.

What type of radio is the weather station using? Are you pulling the data using RTL_433?

Central heating: is there any good way?

Jump

GreatAlbatross @feddit.uk 2mo ago

Boilers are kinda on/off, from a control perspective. The boiler heats water to the set flow temperature, pumps it around the loop, and repeats until it's switched off. The amount of gas used is modulated by the boiler to make the water come out at the right flow temperature. Unless all the rooms in your house are perfectly insulated, or so badly insulated that they lose heat instantly, ad-hoq temperature changes in individual rooms is tricky to do well.

I did have smart TRVs for a while, but actually ended up binning them. So my current solution is: HomeAssistant controlled call-for-heat. This is a relay that when connected, turns the boiler on. Temperature sensors in each room. This allowed me to balance the radiators so they all warmed up evenly, and also feed into the HA thermostat to decide when the heat needs to come on. Manual TRVs in each room set to slightly above the normal target temperature. So they're normally open, but will close if something crazy happens, like someone turning on a fan heater. Timed target temperatures in HA. So the target temperature drops at bedtime, and rises just before I get up.

I also lowered the flow temperature of the boiler, which improves efficiency. I'm not 100% sure what you're trying to achieve in your setup. But adding TRVs to each room (and having one always-open, like the bathroom) would be a good step forward.

Control light without 3rd party app

Jump

GreatAlbatross @feddit.uk 4mo ago

A little late to the party, but yes, I can confirm that Hue bulbs can be controlled directly over zigbee. You will need a zigbee radio if you haven't already bought one (£20-ish). They literally just appear like a zigbee device inside that integration.

You may need to reset them before they will pair. I forget the pattern, but iirc it's on 2s, off 8s, repeated until you see an acknowledgement flash. Sometimes, you'll get one that takes forever, then the next bunch will just hop right on. I have several Hue hubs I still need to offload, as I sometimes buy the combo packs that include another hub.

I also found that the response time was a lot quicker over direct zigbee than farting around with Signiant/Philips' API.

The trick is to buy reasonably open devices, then provide the smarts yourself. If it can talk to / be configured by HomeAssistant, and doesn't require internet to work, it'll probably be fine.

Wet underfloor heating controllers

That's indeed useful information! My boiler control for the central heating has the very useful function of a 30 minute button. Which means even if I torpedoed HA in the middle of winter, I could still get the house warm.
