Had to look that up.

You, @Onoff, @joe90, @Omnibuswoman and my bathroom.

I have only had about 5 Pis connect using host names and not had a problem, but may play sometime in the future when I am not commuting up country every weekend.

Why not try Zero W, they have wifi and BT built in. And a more serious question, why not use hostnames?

Would have been, but need unique and static MAC address now I have taken your lead and ditched using host names. I take it this network is for the home automation system you are designing and coding for us all.

So you flashed your Mac.

Report back as I have not read it since it's release. And there is much more fun things to do, like watch the crowd building outside Derek Thompson MP's office.

I insulated the cupboard they are in as well. Just make sure any wiring can cope.

Man makes his own lithium ion battery pack with a BMS.

I suspect it very much is. But you may want to read this report (then tell us all what it says) https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/198850/hot_water_cylinders_buffer_tanks_heat_pumps.pdf

No need, I will just make up the gossip.

Can't you use a suitably sized buffer tank to do this. Only needs to be able to store a similar useable amount of kWhs as you use in DHW.

Not car batteries. They are designed to deliver huge amounts of power over a very short time frame. Nickel iron may be a suitable option. But which ever way you cut it, no option is going to be cheap.

Seems to be a job site for plumbers.

That looks a good bit of kit. Assuming it can take around a kW of PV added to it, as an inverter it is not stupidly expensive.

I shall tell the postman when it does.

I think there was a thread where someone wanted to fit PV modules to their new build roof, but not connect them, in the hope the SAP/EPC would be improved. Let's not cheat the system, even in jest.

Question: Is this pure or modified sine wave? Answer: Its modified sine wave. I had to return it as my microwave really didn't like the output By S R. on 07 July 2020

It will be done badly. It is basically thee government trying to look like they are doing the right thing.

Damn, never got a chance to see what they said. "There is only one thing in life worse than being talked about, and that is not being talked about." Oscar Wilde

Is this inverter you bought a pure sine wave one. Just taking stab in the dark, if it is not, and the lights/induction hob also 'chop' the power, rather than do it properly then there may be times when all the peaks line up and a higher voltages is achieved. Then there will be times when one is on the way up, and another is on the wat down, which may draw more current than designed. I only have basic understanding of power electronics, not as simple as text books make out.

Was meant to be 'your', not 'our'. I live almost as far from you as o e can get in England. Did go to school in Canterbury.

Nothing compared to the noise our neighbours put up with when you start up your motorbikes (don't ask how I know).

It is all going to be a compromise, but if you can add extra in one place, that helps, especially if it is a side that does not see the sun.
