It's not on the type A connector, it'll be on the type C but type C requires negotiation which the device or a breakout board has to do. Powering off a type C in some way is probably the way to go though as those types of battery packs are more "mainstream" so will be cheaper and more available.

Sort of, pension rights got migrated across when FE colleges were separated from the local authorities. Teaching staff are on the Teacher's Pension scheme and support staff are part of the Local Government Pension scheme, both public sector.

It's a Krone voice block inside a usual voice enclosure. Doesn't look like normal telecoms given the choice of what looks like cat5(e). My best guess would be an intercom system for a block of flats which would also tally with the huge number of outputs on the tv amp. Is this utility room solely...

Does it even need a mains inverter or just a charge controller? What are they powering? Lights? CCTV camera? Mobile phone charging? Off grid solar is all about the power budget.

Redundant laptop PSUs from reputable brands can be a good source of half decent 18-19v PSUs. Your chances of finding one of those with the correct centre pin negative connector are more or less zero though so would require the connector to be rewired.

I seem to recall cat5 cable tied to heating pipes at a previous job's old building and never saw any ill effects, do have to mind kinks and snagging if you're pulling through.

Perhaps over the top for one sensor but Home Assistant has an android/ios app and allows you to easily do notifications based on whatever sensors it can see which can include esphome/esp or zigbee depending on what sensors you want to use.

If it's the same system you've previously posted about the inverters are listed as doing all of the following: Advanced Weather compensation programming Octopus Agile Tariff Ready Octopus Outgoing Tariff Ready Octopus Go Tariff Ready Grid Share Incentive ready Smart export control on both AC &...

DHCP leases are an allocation of an address for a certain amount of time, standards compliant DHCP servers won't allocate an address it's already assigned a lease for but if it's a device where it doesn't have persistent internal storage and it's powered off it's possible. If you have multiple...

Double allocation shouldn't normally occur with DHCP allocation as the client (and sometimes the server) will check if the address is in use. Whilst the information on the router may be useful I'd not rely on it, I'd look at the clients and check which DHCP server it thinks it's fetched an...

Contriving unlikely edge-case scenarios whilst there's any amount of dodgy new kit out there. Brill.

It'll be "permitted temperature rise" or somesuch which may even be measured over different time periods. Given Flameport's test videos of overloading Wagos to ridiculous levels the cables would be glowing red hot all over the place before the connector fails.

It's in their linked knowledgebase/FAQ The approval criteria are different.

Straight runs of surface mount trunking may be alright but I can see them having issues with something going underfloor due to the possibility of kinking or damage and ease of replacement. They'll also want to supply the pigtail, they're not likely to use something customer provided.

Foam will be fine on the pipe and wouldn't damage it, it's sold to seal around pipe gaps and you can use it for damping water hammer issues. If you can get at it with a hair dryer is it not possible to wrap some of the wrap around lagging round it rather than the foam stuff?

Solenoid valves on washing machines are a press-fit construction so when they freeze they rather unhelpfully push themselves apart as I discovered last winter.

Does the utility room stay a little bit above freezing? Insulation slows down heat loss but it might be a case of making sure the room itself doesn't drop too low with some tubular heaters or the like as well.

Tacwise do staples in stainless but even the normal ones are galvanized

Other than not feeling like you're walking on a slab of ice in some properties?

If you have a battery system that's lasting you through to the early hours you may find it better to go with a smart tariff designed around this sort of setup, they have a cheap overnight rate for battery top-up and pay you extra for export during peak hours if the batteries can spare it.
