Warning: I see a lot of installers pushing for all wireless sensors, but after a retrofit job on a 1920s brick house in Springfield, hardwired contacts with a wireless takeover module were way more reliable and saved me two service trips.
The old steel door frames and thick plaster walls caused constant low battery alerts on the new wireless sensors, but the hardwired ones with a simple RF transmitter at the panel have been solid for over a year now, so has anyone else found that a hybrid approach is better than going fully wireless?

Feel for you on those callbacks, that's brutal. Pushing all wireless in a place like that is just setting yourself up for pain. Makes you wonder why some installers are so stuck on one method. The hybrid way seems like the only thing that makes sense for old solid houses, doesn't it? Glad you found a fix that actually works.

Wait, you had to go back TWO TIMES because of low battery alerts? That's a nightmare for any retrofit job. Those old houses with plaster and brick are basically a dead zone for wireless signals. Going hybrid with hardwired sensors and a wireless panel module is honestly the only smart move. It saves everyone a huge headache later. Pushing all wireless in a building like that is just asking for callbacks.

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.
