    Also posting the wiring helps others to help you. Fitzing is easy for this task

  • RE: WeMos D1 Mini Gateway + Relay

    What type of relay are you using? You can only use one with opto couplers. You can regonise it, because it has a vcc and a jd-vcc pin. Power the jd-vcc with 5v and vcc with 3v. The vcc is for TTL lvl control and the jd-vcc powers the 5v relay. Without this version you can not hook up a relay to a 3.3v microcontroller. Because the high state is barely high enough to drive a normal 5v relay

    @anderBAKE Be careful to which pin you hook up the relay. Most Mini D1 pins are shortly being pulled up during boot up. That short spike can damage the device you've connected to the relay. It's why I avoid using the Wemos D1 mini with relays. I believe d0 is one of the pins that's not being pulled high during boot up - but not sure.

  • RE: 💬 Relay

    @mfalkvidd I'm in an older version I discovered. Ran across more small differences.

  • RE: 💬 Relay

    Not sure if it ever has mentioned before, but the first example contains

    // Enable and select radio type attached
    #define MY_RADIO_RF24
    

    Which results in a compile error

    MySensors.h:287:4: error: #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.
       #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.
    

    It should be:

    // Enable and select radio type attached
    #define MY_RADIO_NRF24
    

    And then it compiles and works 🙂

  • RE: Where did everyone go?

    @chbarg In all honesty, I think ZigBee is much older than mySensors. It's a pretty old standard. But it was very expensive to use, but since Philips and Ikea used it in their smart lightning it has become very cheap. Zigbee is used in commercial products, whereas my Sensors is just a nice and - more reliable - option for those who like to build their own stuff. I say more reliable, because the Ikea stuff I use is not always available. At least I have troubles with it. Also the batteries in the remotes drain really fast. Specially when attached to the gateway and night directly to a device

  • RE: Where did everyone go?

    @feanor-anglin it really looks very interesting to me. And if I'd renovate my house or bought a new house. I'd go for wired for sure. I'm running my sensors with NRF24L01+ for over 7 years now. And I actually didn't notice any problem. It's very reliable, but I admit the radio is very picky on it's power. Most problems I ran into where all power related.

    Why I've been absent for a long time has several personal reasons. I needed to finish a study I was following next to my job. And after I finished it I had some health issues. And when I decided to get back into it. My dad passed away. We're now cleaning out his workshop, he earned his living as an electronics repair man. I'm keeping the stuff I can use, like the Fluke meters - although they are 20 years old they still work good - his lab power supply and stuff like that. It's also to moment to redo my own workshop. Because the organization was completely lost. I ordered a lot of parts the last years but never took the time to store them.

    So hopefully this will al be done and I can finally finish some of the projects that are laying on my desk for years

    @monte We must have a conversation in a chat or something. to me Ikea is not usable at all. Usable meaning effictive, efficient and looking good.

    @monte As a UX designer I dare to differ. HA anno 2021 is overly complicated. No one needs to know how to wire a light fixture. You just change the light bulb when it's broken. Or if in some cases hire an electrician.

    I believe I can design things much much simpler. And make it usable.

  • RE: Where did everyone go?

    @NeverDie I'm actually looking for a team backend and frontend to help me reinvent home automation. And give it back to all people, not only the technical ones. I've done quiet a lot of pocs to test me ideas. Preferably Python back end, so I can do some help in coding xd

    Current HA systems are difficult. In comparison to the real world, it means that when you want to change a light bulb, you have to completely rewire the fixture in which the lightbulb you wanted to replace was in.

    I think it's too complicated ^^
