Re: New Pi3 no wire ethernet

Looks like it is hardware issue. Predictable interface names are eth0 and eth1 also wlan0. Hmm I guess I have to return it back to seller. Maybe this evening will fight a little bit with it but I almost lost hope.
I have put the same card in different pi3 and TA DAM! Works!

New Pi3 no wire ethernet

Hello I have brand new rpi3 with ethernet wired connection. rpi does not pickup dhcp (it fully functional). sudo ifup eth0 ends up with device not found (ifup: unknown interface eth0/eth1) but ifconfig clearly states that eth0 and eth1 exists. I'm using clean stretch lite form 9 september. I tried u...

Re: My Pi 2 is toast, can I use Pi zero?

The only problem is lack of ethernet card - so how about POE? You have to add USB card or wifi.

Quick way to update weather station software to latest GIT?

What is proper and quickest way to update WS software to include all commits since my install? I don't want to reinstall whole station and reinsert my credentials? Any update script out there?

Re: Ambient Temperature +5 degrees

Does Figaro TGS2600 include heater? Most of gas sensor need to heat up before you can get reliable readings. If so ... that is why only ds1820b give reliable readings.

You can find this sensor here: http://www.ebay.co.uk/itm/Spare-part-fo ... SwBLlVNi-U

DS18B20 is most accurate. In those two other temp sensors are only used to correct main purpose readings.

Re: Ambient Temperature +5 degrees

I would say that messing in code is not good idea, until all schools do the same change.
If you do it on your own station only you make pointless uploading data to oracle database. While you create local visualization of course you can do it, but uploaded data should be intact.

I did that but it makes apex data not consistent. Each school will fix that in different way. It is a moment that RPF should step in with solution for all of us.

Re: Ambient Temperature +5 degrees

This sesnor is not a digital termometer. It is mainly used to calibrate humidity - the same as temp sensor in Bosch. IMHO this is bad design and there should be at least lm35 or ds18b20 out of the air sensor board - board itself makes temp reading false. Temperature offset is not a solution imho.

Re: No internet through etheret cable.

Do you receive IP configuration via DHCP or did you configure DHCPClient on your own? It looks like local dns is working but firewall at your school does not allow new machine access internet - ask your system administrator for help.
