    • RE: What did you build today (Pictures) ?

      Today I have finished work on control center for my smart home. The box includes a Raspberry Pi 3, gateway, ethernet switch, power supplies 5V and 9V. Audio input jack, ethernet and AC line cabels out from the box. Maybe, a GSM module should be included to the free space too (i will thinking about...). I am going to install this box in the near future.

      Looks neat! How did you do the cutout of the sides of these enclosures?

      No magic, this is the work of the CNC...)))

    • RE: 💬 MDMSGate

      Hi @berkseo. Thanks for the suggestion, but could you describe in more detail? As for my TODO list, there is already a task to add 485 interface to the gateway. My latest device "xRoom" have this interface.

      ps/ Where have you gone?

      I have been working on "xRoom" shield. A small announce:

    • RE: 💬 MDMSGate

      I am going to production a new batch of gateways, but before that I want to upgrade it. Does anyone have any suggestions for improving current version MDMSGate?

      Hi @blackchart,
      Unfortunately, all devices are sold out. Further production is possible only when ordering more than 10 devices (in this case, I also can modify the device to suit your needs).

      Hi @aramko-aramko.
      Unfortunately, this model is already sold. You can look at the upgraded version of this device - MDMSNode "Lighting" Rev 1.1.

    • RE: 💬 MDMSGate

      Hi @animal64, we are glad to welcome you in the MySensors community.

      I don't use MQTT, but one of users, who took the gateway, did some work in this direction, you can find on this link - https://gitlab.com/denissp/mdmsgate_mqtt/

      Yes, for each type of radio module you need your own gateway, its own subnet. This means that two gateways are needed.

      If you have any questions, please contact us, we will always be happy to help 😉

      @dbemowsk Yes, it is a factory case, and before the changing it looked like this :

      0_1550728110717_Enclosure.jpg

      At the moment this is termostat, but I will not limit myself to this)) The purpose of the panel will be determined by the software project loaded into it. I will describe this in more detail when I publish the project.
