  • SCT-013-030 Energy Meter
    Lawrence HelmL Lawrence Helm

    I never got this going, have to play around with it again, but one thing I did do wrong was put the clip around both wires, instead of just the positive. I.e. putting it around + and - will give 0.

  • LCD node for the Build section.
    Lawrence HelmL Lawrence Helm

    Thank you, I did find some examples, but when I tried removing and including code I would get a blank screen. But besides that, its a great thing to have under the build section. I'm sure others would benefit, making an awesome thing even better :)

  • LCD node for the Build section.

    Re: LCD displays

    One thing that is missing from my sensors build part is an LCD node, say I have a temperature sensor in the garage and want to display it on an LCD node in the kitchen. There are many projects that have an LCD display but nothing simple for the non programmer like me :)

    Thank you

  • Round water tank level sensor
    Lawrence HelmL Lawrence Helm

    @Boots33 Have you thought about sending the days available. i.e. calculate daily usage and divide that by the water that is still available? would have to roll the numbers i.e. say take the last two weeks of how much the water dropped in a day averaged out... if that makes sense. :)

    @dennis_henk nope but looks similar to a roller blind, you can check out rflink and domoticz :)

  • How does MySensors actually work
    Lawrence HelmL Lawrence Helm

    @palande.vaibhav o.k if all connected o.k, it should show up, remember it will send something when the temperature changes so hold your fingers on the temperature sensor, and it should show up...

    For a start just install domoticz, or other software on a pc (controller), connect a gateway to that pc and make a sensor, then go to the software website and read how to add the gateway and sensors :)

    Lawrence HelmL Lawrence Helm

    Hi,

    I had an idea, for anyone entering the contest, and for anyone that has ideas, but not the knowhow could post it here too :)

    So some people have used V_text to send a temperature from the controller to a node with an LCD display. Which I'm still planning on implementing my self.

    But for something more interesting that could be implemented, are gauge displays or something like the following:

    Great work, I tried to get the other v_text example working to do the same, but gave up, will give this a go! Thanks for sharing :-)

  • Boiler control from MAX! Cube to Drayton Boiler via Raspberry Pi/Vera/Mysensors.
    Lawrence HelmL Lawrence Helm

    Just a question, are the eq-3 radiator valves quiet? As I have a wood burner and my thought was ramp up the heat when the fire is lit, but then once the rooms are at temperature, close the valves to minimum to keep the fire going for as long as possible, this is usually when we are sleeping :)

    very cool, might have a go at some stage to try and use the nfc variant...

  • Basic Lcd Node
    Lawrence HelmL Lawrence Helm

    Did you ever get this going if so can you share the code? My project is similar have a few temp sensors around and send them to an lcd screen node. Lcd can be a repeater to the gateway for logging on domoticz, also if so what extra code did you add on the temp sensor side?
