I have been getting to grips with Home Assistant (hassio)<\/a>. (This was after attempting, late at night and tired, to update OpenHab… It didn’t go well and though I had solid backups I knew I would need to do a full restore and have kept hearing about Home Assistant. I wanted to give it a try, and found it is so much better than OpenHab. I had everything OpenHab had and more in one morning of play. Everythign is so much easier).<\/p>\n\n\n\n

So the more I got in to hassio the more I kept hearing about Templates<\/strong>. Hassio is well documented but there are no examples at all. I can read them but miss the point because, typiccally, I read too fast.<\/p>\n\n\n\n

So when the Templating documentation<\/a> said:<\/p>\n\n\n\n

\n

Templating in Home Assistant is powered by the Jinja2<\/a> templating engine. This means that we are using their syntax and make some custom Home Assistant variables available to templates during rendering.<\/p>\nhttps:\/\/www.home-assistant.io\/docs\/configuration\/templating\/<\/cite><\/blockquote>\n\n\n\n

I didn’t realise this meant “custom code”. That would have helped. Template = Custom Code in Jinja2!<\/p>\n\n\n\n

I went in to the Developer Tools > Template and had a play (with the help of avideo by “Smart Home Junkie”<\/a>) I found that I could easily get the value of things using {{ states(‘the_thing’) }} (I also found that the Dutch word for curly bracket is “accolade” which is way better to my ear).<\/p>\n\n\n\n

With my new knowledge I made my first Template to show the current rate as a read only thing so I can display is safely. <\/p>\n\n\n\n

    \n
  1. A name – this is what you look up later and is turned in to a spaceless name, this one would become current_rate<\/li>\n\n\n\n
  2. The Jinja2 code<\/li>\n\n\n\n
  3. Preview<\/li>\n<\/ol>\n\n\n\n
    \"\"<\/a><\/figure>\n\n\n\n

    I made a sensor called “Current electricity period” and magic happened when creating a dashboard.<\/p>\n\n\n\n

    I know it is basic knowledge, but I needed to make this first step. I think I am away now.<\/p>\n","protected":false},"excerpt":{"rendered":"
