Today was my last day at work. It was a rather relaxed day since I already finished my work the only thing I did was giving Johnny a brief overview on how he can run my Perl scripts.
We also talked a bit about how we would actually get it to work with an BMS only to realise that this could be a lot of work but it should be possible to do.
I also gave Lawrence my details in case they need help with my perl scripts. Around lunch Rosie brought in some sweets as a last gift to say goodbye and they even gave me a little card.
They even used german it might not be proper german but hey that’s what makes it even more special

Well as nearly everyone told you already this is our last week here in Belfast.
So I spent most of the week with working on my perl script.
I finished it Yesterday afternoon. I spent this morning with finishing my Europass and checking if all of the paperwork is done. In the Afternoon I gave Johnny a brief overview how my Script works and what he has to adjust for each Network.
I also gave them my contact details in case they need help with my script.

This week I continued the task Lawrence gave me on Friday afternoon. He wanted me to see if its possible to trigger an unscheduled event from and external source. So I started to do my research and quickly discovered that indeed is a way to do that. So I started to write a little Perl script that does exactly that after a few minutes of research how to write a HTTP SET request in Perl I finished my little perl. But there was a little problem the answer from the Redwood Director was always accessFailure which mean I try to do a Set request on a portion of the Data Model that does not allow set requests which was strange since that part should allow Set Requests after a few minutes of looking through my code I realised what I did wrong I simply put in a wrong name that I tried to access. After getting rid of that I finished my script and tested it a few times and it works perfectly fine. I’ll show it to Lawrence on Friday since he is not in the Office tomorrow. We’re also doing a „night out“ tomorrow we’re going bowling and grab some food afterwards. Its basically to say goodbye in some way I know it’s still a week left but a few of my coworker aren’t there next week so we do it a bit earlier.

On Thursday I continued my work on my task to access the Redwood API and pull out certain data.
It took me a while to get used to Perl and the Syntax but with a little bit of help from Tim. I managed to make a big progress. I was able to pull out all the Data I needed and finished my Perl Script on Friday afternoon.
But only so far to reach the point where we would contact the BMS but I don’t have any documentation about a BMS so I can’t program that part.
My new Task is to see if its possible to trigger an event from an external source for example an BMS.

On Monday I finished my VBA Macros for excel to automatically create graphs from a .csv file.
I showed my solution to Lawrence and Steven they both liked it. I gave Steven a brief overview of what I did and what the code does he is the one that keeps my code maintained after I leave in a bit over two weeks.
Afterwards Lawrence gave me a new task as the title already states its about API Our Redwood engine got a API to pull out certain data (movement, temperature and a few more) my task is it to find a way to pull out the data when the last movement was registred from one of the sensors and if it was more than X minutes ago it should send a signal to a BMS (Building Managment System) to shut down the heating in that room/area. And of course to turn it back on if someones enters a room. The documentation was about 30 pages long and it took me a while do fully understand it. Today I finished my first perl programm that is able to send a HTTPS PUSH request to pull out certain data. The next Step is to scan the String for the data that I need. The last and I guess hardest part is to get it work with a BMS since our Building doesnt have one so hopefully I find a way to test it somewhere/somehow.
