False start toggle component missing and my solution

Hi all,

I’m sharing this log to document an issue I encountered — the mysterious disappearance of the [LB FalseStartToggle] component — and how I eventually resolved it. This problem confused me for quite some time, and I hope this post helps others who might run into the same situation.

Background

Everything was working fine with my Ladybug Tools components until I tried to access some elements from a fellow’s file that may use Legacy components. During this process, I installed Honeybee Legacy in order to find [Honeybee_Item Selector].

Unexpectedly, this caused my [LB FalseStartToggle] component to go missing.

Troubleshooting Steps I Tried (Unsuccessful)

  1. Pollination One-Click Installer:
    Reinstalled everything — but [LB FalseStartToggle] was still missing.
  2. Grasshopper Install Script for LBT 1.8.0:
    Used the script to uninstall and reinstall Ladybug Tools — still missing.
  3. Manual Component Download:
    Downloaded a .gha file from this post:
    Image viewer in latest LB release - #5 by minggangyin
    The component worked as a basic Grasshopper element, but not as an official part of LBT. It didn’t restore the original [LB FalseStartToggle] in my older files — not useful in my case.
  4. Ironbug Legacy Component:
    Referenced this post:
    Base type is missing for false start toggle - #5 by c.zou - Grasshopper - McNeel Forum
    I downloaded Ironbug.LBHB_Legacy.gha, which gave me a component named [Ladybug FalseStartToggle], but it was still not the correct one — it has to be [LB FalseStartToggle] — and didn’t fix the issue.

Solution (Finally Worked)

Eventually, I tried reinstalling different versions of the Ladybug Tools plugin using install scripts from Food4Rhino — version 1.8.0, 1.1.0, 1.6.0, 1.1.0… nothing worked. Not a recommended strategy — just desperate.

But finally, when I installed version [ladybug-tools-1-7-26], my [LB FalseStartToggle] came back.

So if you encounter the same problem, try rolling back to LBT 1.7.26 — it might save your day.

Hope this helps someone out there!
