Pans for induction need to be magnetic (iron, steel, etc).But, my other cast iron has a ridge on the bottom, instead of sitting fully on the base, so does not seem to work. Cheapo aluminium pans don't work.

I think my pans are flat on the bottom so should work.

Finally seem to have local access code for devices that is useful outside of some ones noddy example. with the available "nodes" if you had 100 light bulbs you'd literally have to write 100 programs to properly control them. Ironically I'm still for completeness fixing the dumb example for edge cases it doesn't cope with.

Our induction range just has power options from 1-10. The only brain box things it does outside of my control (other than oven timer) is to operate the cooling fan to keep the inductiony bit from overheating.

Manufacturers can make non-ferrous pans work with induction, they just include a steel or iron disk in the bottom of the pan. Our main hassle was finding a moka pot built for induction, but they certainly exist

Latest addition is a "glowstick" yet another device that plugs in, manages to read the smart meter, but then refuses to communicate locally

Instead on request they give you a "mqtt" end point from which you can get the reading every 10 seconds.
I'm calling that a glass half full and the data returned even potentially has a solar export reading.
It also has the gas readings.
More disturbingly the 628 page document they refer you to, to figure out what the readings are

include data like "physical attack on prepayment meter" as well as an awful lot about allowed credit.
Smart meters are not exactly there to help!

has it got a code for "i have been tazered and reset myself to full credit"?

https://www.npmjs.com/package/node-red-contrib-tuya-auth Published 18 hours ago and has notched up 111 downloads I was expecting some interest to emerge, but that's rather a lot.

get the data from the things into the box is very useful, well done so far

I have been helping a friend. Choosing modern panels (370-400W per panel) and being aware of the single phase limit of 16 Amps, we ended up with a panel array of 10 panels (3.68kW/370W=10)

We upsized it to 12 panels to give spare capacity on cloudy days.

With regard to shading, panels either come with string inverters or edge inverters - the latter are slightly more expensive BUT with the string inverters the whole string (usually 2 strings in an array) is limited to the power output of the weakest (shaded) panel(s)

With an edge inverter, each panel delivers a maximum power even when a panel is shaded.

Final thought, panels generate energy even when the sun is not out (overcast). Typically, in September, a lightly overcast day drops power generation to about 40%. So 3.68kW generation would drop to 1.48kW.

lots to think about. see panel prices at midsummerwholesale.co.uk

As Dpack says, welcome. Thank you for that information. It is very useful for us as part of the panel could be shaded some of the day.

uk solar panel installation crowdfunding half a power station in a year might not be the most cost-effective way of making not-fossil leccy, but it helps, and it gives strength through dispersal which is sensible with critical infrastructure
