Re: Reinstall Raspberry Pi with Docker containers Domoticz etc?

I suggest looking in to IOTStack. It's a system for installing docker plus various IOT containers on a Pi. Takes care of all the configuration of each container

Is sunlight hitting the sensor directly or somewhere nearby? I have a temperature sensor that's in direct sunlight for about 10 mins in the afternoon during the winter.

Re: 2G RPI 4B base model not available UK

I've been on the lookout for Pi4 2gb but keep missing them being available. CPC sometimes allow backorders but they're charging £40 a unit for 2gb model.

The Digi-key price including VAT is £30.75. Not sure I want to take the risk on import duties at the moment.

Re: Raspberry Pi 4 2 GB Discontinued? No

Interesting to see 4 of the 5 Raspberry Pi recommended UK resellers are out of stock of the 2gb model.

The exception is CPC who are charging £40 (who are part of Farnell / Element 14).

Re: Raspberry Pi 4 2 GB Discontinued?

Pi 4b 2gb (and 1gb) no longer listed on CPC's website

Example here

So it does look like it's been removed rather than just no stock.

Yup, I bought one, sealed element 14 packaging, new 1.2 model, £34 inc delivery. Seems in full working order.

I wondered if the buyer had them in stock and thought they were the older model, so selling them off cheap.

Pimoroni were saying their heat sinks only drop the CPU temp by 2 degrees.

I'm using their FanShim and it's dropped the temp by 30 degrees. Low profile and quiet.

Re: where to buy rpi zero 1.3 for builing a cluster

Try Pimoroni. They ship worldwide.
https://shop.pimoroni.com/products/raspberry-pi-zero

You'll have to place an order for one Zero per day.

Including P&P to UK, that would make each Pi Zero £7.16 which is still a fair bargain.
