What temp ranges are these good for? Can it run off solar+battery?

How are you protecting against supply chain attacks?

“Driver”

HP and HPE are separate companies.

About 180w. I’ve tried maximizing power efficiency by turning on eee, disabling unused ports and Poe, limiting services/containers to essentials, underclocking a raspberry pi, turning off equipment when not in use if it supports WoL reliably or has ipmi.

You can buy a rack that’s sound insulated and uses a really large exhaust fan. It’s still going to be loud unless you keep the room cool.

Best bet is to flip it. The components might be ok to reuse, the mainboard probably is not atx.

But you can probably find a compatible mainboard for cheap.

Use a cloud host for offsite storage unless you have a friend that will swap offsite backup storage with you.

Probably not. This rosy app is tailored to salon stuff and honestly looks really good.

Sounds a lot like a library system.

I haven’t seen a water heater with one though.

Pitfalls:

You have a small space: heatpumps need airspace and it needs to circulate. An enclosed closet won’t work.

Your heater is outside: heatpumps pull air through and dust/cobweb buildup isn’t good.

You dont have electricity to the heater: heatpumps need a decent cuirruit size to run. Some can run off a small 120v circuit.

You didn’t size right: heatpumps can’t keep up with sustained demand usage. A larger tank offsets this.

You can keep your old system too though. Just put your hybrid before it and set your temps at like 125 for the heat pump and 120 for the boiler. Your boiler will rarely need to run unless you have sustained usage, a power failure, or it needs to bring temps up in the water it’s holding.

How? I’d like to make my own too.

I don’t think about Israel this much.

Is it implemented the same way beer company websites ask for your age?

Your basically setting up and email server with a gateway service for inbound and outbound mail delivery.

This is typically called a secure email gateway. I’m not sure if there are any designed for personal use.

Is GLPI + OCS Inventory still around?

I got this because it’s almost fully enclosed. Most of the noise comes from an open rear door which this doesn’t have, and an open front door which this sort of has. It’s not very loud when the hvac is set to a reasonable level, even though it’s pulling air through 4 fans on the top.

I have additional sound deadening material if I need to apply it but I’m not there yet.

I’m eyeing 3-5 more 1U servers though so maybe I’ll need to do it.

Business in front…

Unpowered free 48 port switches are cheaper than block off plates.

Can’t hear either over my tinnitus
