Simple sleep/measure/send/sleep application help please!

[skittlez]

Hi, my previous post has been up for a while with no comments...
Can anyone point me to a simple tutorial that details the steps to
* set up an esp8266 that goes into deep sleep for 5 minutes at a time
* when it wakes up, it reads from a sensor (e.g. a BME280) and sends this to a Syslog server once and then shuts down.

That's all I really want to do, I just need to be able to do it reliably which it isn't at the moment

If Syslog itself is problematic, please let me know!!!

Any help hugely appreciated, I can imagine that this is something that a lot of other people probably want to do too.
