    • Relialbe presense sensor

      In the office I have industrial light sensors which don't work properly - when I enter a room the lights are turning on but after period of time it switches lights off like there's nowhere in the room.

      I'd like to install PIR/presense sensors in bathroom but definitely don't want to have ussues with turning lights off because sensors don't work properly.
      Does anyone has a solid experience in building / using presense sensors?

    • Repeater node logic

      I'm using MySensors under Vera UI7 in the environment where radio power is not enough. Repeater feature logic is not very clear for me and I have some questions:

      • can a node work via many repeaters? I mean, if a node is really far from gateway, can it get data from the gateway via many repeaters, for example: Gateway->Repeater1->Repeater2->Repeater3->Target Node ?
      • can a node can be included via repeaters? I mean, does inclusion mode work if the node not connected directly to gateway, but via repeater(s)?
      • do repeaters load network and/or gateway? Will tens of repeaters affect network performance and is it worth to make each node a repeater by defaul?

      Thanks!

    • RE: Measuring network signal level (NRF24L01+)

      If there's no ready-to-use sketch, then which field I need to track to understand RX level?

    • Measuring network signal level (NRF24L01+)

      I have some strange issues with connection between node(s) and gateway. All NRF24L01+ based.
      To analyse this I plan to create a device to measure signal level. Is there any ready-to-use sketch for this?
      Thanks

    • Looong wires for digital input lines

      I have long (~10m) wires connected to Arduino Pro 3.3V ports. All of them used with just debouncers, so I connect these wires with GND to switch something.

      Shall I do something special to decrease noise or any other potential problems?

    • RE: Re-establishing connection with gateway

      I found problem in my code: my node sends update if only it has value changed, which can take really long.

      @flopp, "it will start to search for a Parent after 6 failures" - does 6 tries happen automatically or the node need to send something 6 times?

    • RE: "Last update" node field in Vera interface

      @hek, many thanks, changed the format and see full info now!
      Question about this Last update value: does it show when value was changed for Vera or this is time when the node sent last value (even if the node sent same value as before)?
      I mean, does it show time of last communication of with the node, or time when value was changed?

    • RE: Showing N/A instead of last stored temperature

      @r-nox but not clear what the time there really means.

    • RE: Showing N/A instead of last stored temperature

      @r-nox, Device List scree, "Last update" field under each node (not device/sensor).

    • RE: Most reliable light switch

      @DavidZH, sounds promising. Give me something for tests, I will spend next few months on this.
