Those newer Samsungs are a total pain to work on, lol.

That's a really good point from @the_stella about the hybrid setup. Honestly, the bigger issue with those old houses is the inconsistent voltage on old wiring, not just the signal block. A wireless panel can still throw fits if the power feeding it is noisy. You're right that all-wireless is a bad plan, but even a hybrid system needs a very clean power source to avoid its own weird problems. A good line conditioner or a dedicated circuit for the panel is just as important as the sensor choice.

Four minutes for a coffee? I need a faster hobby.

I was refreshing the thread when it locked at 437 replies. The mods posted a reason about "repeated rule violations" not a count. The 500 thing was just what people guessed after. The new rule was a mess, it basically just told people to go argue about ships in the fan art section instead.

That first working script is the best feeling, honestly.
