Hey,

I have a Raspberry Pi installed in my greenhouse for some years. Recently i have some issues with it.

- Crashes almost every day
- After every reboot i have to reset the PI pw

Is there some log where I can see what is going wrong?
Updated already with the latest software updates.

Thanks!

Hey, A while ago I moved from hosting everything on my raspberry to the cloud, also the database. I searched for a online free alternative to put my sensor data in = Google Firebase. I want to cleanup the database, i only want to keep data for eg. 1 week. Does anybody knows how to do that? I have to...

@DougieLawson it's this version created with Etcher.

Hey,

i'm searching a tool or a kind of code to backup my Raspberry every night to my Synology. A 'dump' should be perfect but I don't know if this is possible over the network with a working Raspberry.

Some one has any experience in making a dump over the network?
Let me know

Thanks!

Hey, I have a Microsoft USB webcam connected to my raspberry PI 2 B, but sometimes i've got a totally white picture and sometimes a bit of a normal picture. See attachment, it's like the picture is over exposed. It's something that can be fixed with some changes on the code? I've added already a kin...

Combining Dom's SQL with mine SELECT timestamp, temp, humd FROM value WHERE timestamp BETWEEN date(date_sub(now() , INTERVAL 1 DAY)) AND date(now()) that's probably easier than doing the date maths in python. date_sub() works like date_add() https://dev.mysql.com/doc/refman/5.5/en/date-and-time-fun...

dverleysen

It's a Very Bad Idea™ to give columns or tables created with any SQL engine names that match that system's data types, that will bite you on the a*** one day. Also your temp and humidity columns are numeric values, so why have you defined them as varchar(10)? Define them as float with a sensible ma...

dverleysen

No, I added this afternoon an extra field 'timestamp' to my tabel, and it has already some data

timestamp = 2016-01-31 15:18:40
date = 2016-01-31
time = 15:18:40
temp = 23.5
humd = 85.0

When I put the query of "rpdom" in phpmyadmin, I get an error
see attachment

dverleysen

When I use this query Select time from value order by date desc, time desc limit 5 I get this result 14:35:02 14:30:01 14:25:02 14:20:01 14:15:01 As I said earlier, that is what you asked for. Your query specifically states to sort time (and date) in descending order - i.e. the biggest one first to...

I changed the type of the field time and data time = type time date = type data But I have the same result as before When I use this query Select time from value order by date desc, time desc limit 5 I get this result 14:35:02 14:30:01 14:25:02 14:20:01 14:15:01 But I want this result in reverse ord...
