## Description

Bosch Smart Home outdoor siren Mounting the Bosch Smart Home outdoor siren in a prominent and visible location on the exterior wall is a preventative measure which allows you to protect your home from burglars. In case of a break-in, the sirens also emit a loud alarm sound. This can be set individually at up to 100 dB. The flashing red strobe light is visible from a long distance away, and when this is triggered, it can alert neighbours who can call for help. The intelligent networking of the alarm system with the Bosch Smart Home system also means that you will receive a push notification on your smartphone. This gives you the option of taking measures or calling for additional assistance even when you are not at home.

Review: Contentissimo della scelta. Mi sono affidato al sistema di allarme Bosch perchè per me più completo per le mie esigenze (cercavo un sensore da porta/finestra con sensore a vibrazione) ma anche le caratteristiche di questa sirena esterna sono di tutto rispetto: 1. Ha due fonti di alimentazione primaria (solare e 230V) con la batteria tampone 2. Dall’app puoi configurare la potenza della sirena (in decibel), la sua durata e quella lampeggiante quando scatta l’allarme 3. L’ingombro è minimo e l’installazione a muro davvero semplice (tenere in considerazione che il collegamento alla rete necessità di un punto di alimentazione che deve arrivare nel retro della sirena) 4. La configurazione è semplice e c’è a possibilità di testare il segnale prima di installarla in modo da evitare forature del muro prima di sapere se nel punto individuato il segnale con la base è abbastanza forte C’è anche la possibilità di collegarlo a un sistema di allarme classico ma, non essendo il mio caso, consiglio di approfondire meglio prima dell’acquisto.

### ⭐⭐⭐⭐⭐ Review
*by T***D on 11 October 2025*

As any Home Assistant enthusiast knows, the automation journey is addictive! After successfully integrating my pre-existing burglar alarm with Alarmo, I faced a common frustration: my old battery-powered siren was constantly going flat. The hunt was on for a reliable, maintenance-free replacement, and a solar-powered Zigbee siren seemed like the perfect solution. My initial attempt with the cheaper Neo Tuya alarm siren was disappointing. While the price was right, critical entities in Zigbee2MQTT—like the live battery percentage and solar charging status—were either non-existent or completely unreliable. I needed a robust device. My research kept pointing to only one viable, Z2M-compatible alternative: the Bosch Outdoor Siren. While the current price of around £204 is certainly "stupidly expensive," I managed to snag it during a Prime Day deal, which offered a substantial and much-needed discount. The Bosch siren is an undeniably premium piece of kit. It's very well-built, giving me confidence in its outdoor durability. The large solar panel is intelligently mounted within the alarm box itself, and the siren is genuinely loud—a significant and reassuring step up from the Tuya mode (See my review video) ⚙️ The Zigbee2MQTT Pairing "Secret" Connecting it to Home Assistant via Zigbee2MQTT was surprisingly a breeze, but it requires one crucial, non-obvious step: the Install Code. First, I removed the back plate of the siren. I scanned the QR code with my phone, which generated a long, unique code (mine was 96 digits). In the Zigbee2MQTT UI, I navigated to Settings > Tools > Add Install Code and pasted the QR-generated string. Z2M instantly found and configured the siren. I left all the internal dip switches set to their factory default "on" position, and it worked flawlessly straight away. The key selling point for me is the deep integration and data exposed by Z2M. I immediately linked the device to Alarmo, and it functioned brilliantly as a professional-grade alarm system component. Unlike the problematic cheaper sirens, the Bosch unit exposes all the crucial entities: Live Battery Power: Showing the exact battery percentage. Solar Charging Volts: Displaying the current voltage being generated. This live data gives me complete peace of mind, allowing me to monitor the siren's health directly from my Home Assistant dashboard. Even on a recent cloudy, dull day, I was pleased to see the battery was already charging at 18V and the percentage was steadily increasing. The Bosch Outdoor Siren is a highly recommended product if you're looking for a great quality, reliable siren that integrates seamlessly with Home Assistant and Alarmo. Yes, the price tag is a hurdle, but for the peace of mind, build quality, and perfect, fully functional integration into a local smart home security system, it is well worth the investment. It simply works—and that's invaluable. If you found my review helpful please let me know by clicking the Helpful button below! Thanks
