  • Reolink Duo 3 PoE surveillance camera tested against 2 RLC 810A

    A man stands thoughtfully next to a large question mark, with three Reolink security cameras and the Reolink logo displayed on a gray background, highlighting Reolink’s commitment to smart security solutions. www.commaik.de

    In my latest smart home project, I replaced my two Reolink RLC-810A cameras with the Reolink Duo 3 PoE surveillance camera with dual lens. I was particularly interested in whether the 180° detection of the Duo 3 PoE could actually improve the monitoring of my driveway and carport. With its 16-megapixel resolution and 2-way communication capability, the Duo 3 PoE promised superior technology and more comprehensive security. But would all the effort and financial investment really be worth it or were the two old camera models better? I would like to explore these questions in this blog post.

  • Designing a smart and efficient garden kitchen – installing lights, sockets and water connections

    Modern garden kitchen with a wooden roof, barbecue grill, counters, and bar area illuminated by soft yellow and purple LED lights, set against a twilight sky for an inviting light-filled outdoor retreat. www.commaik.de

    The development of my garden kitchen has made significant progress, particularly in the areas of electrical installation, water installation and the integration of smart technologies for lighting and control. I’d like to give you some insight and practical tips on how I overcame these challenges, from carefully planning the lighting to installing smart sockets and light switches that enable flexible and efficient use.

  • Build your own garden kitchen – solid half-timbered roof with OSB and welded sheeting for the outdoor kitchen

    Partially constructed garden kitchen with unfinished concrete block walls, a wooden roof, and a grill inside. The structure sits in a backyard, surrounded by trees visible in the background. www.commaik.de

    When building my garden kitchen, the next priority was to construct a robust wooden roof to create a sheltered area for the gas barbecue and work surfaces. The roof was to consist of solid wooden beams which I wanted to screw directly onto the walls made of glued aerated concrete blocks. The covering should be made with sheet piling and OSB boards. My plan also included fitting the guttering, the end plates and gluing the welding membrane to make the roof weatherproof. In this entry I will show you step by step how I carried out the individual installations and what I had to pay particular attention to. Of course,…

  • Build your own garden kitchen – plan and install the electrics

    Partially built outdoor wall of white concrete blocks with exposed electrics, a level tool, and a hammer on top—ideal for a future garden kitchen. A canopy and stacked firewood appear in the background. www.commaik.de

    When building my garden kitchen, the electrics were one of the biggest challenges. In addition to the right cables for the power supply and the perfect positioning of the sockets, proper fuse protection was of course also necessary. It should also be possible to use a TV and a sound system in the garden kitchen at a later date. So I also had to plan for network and audio cables and install them in the garden kitchen.

    The renovation of our garden terrace has been in the pipeline for some time. The larch wood of the substructure could no longer withstand the loads and slowly disintegrated. So after ten years under the open sky, it was time to give our terrace a fresh update with WPC boards. In this article, we take you on a journey of renewal – from the initial idea to the finished result.

    In this article, I describe how the new pool liner was laid, glued and welded to the walls and floor of our new pool. The pool steps and the sunbathing area in the water were lined with a special pool liner that makes the surface non-slip. The new pool in the garden was built with concrete formwork blocks and replaces our old steel wall pool. Before I can lay the liner in the concrete pool, some preparations are necessary. In this article I will show you every step.
