7. 7 doporučení + 5 chyb při smart home

**7 doporučení:**

1. **GDPR compliance kritický** — consent + DPIA + ÚOOÚ enforcement zvyšuje risk score +25 při non-compliance

2. **Cybersecurity audit povinný pro premium + enterprise** — 100-500k Kč investment chrání proti breach + ransomware

3. **Security-cameras + monitoring-water optimal combo** — combined 15+12 = 27 % insurance reduction

4. **Local-first architecture preferred** — Home Assistant, openHAB, KNX (proti cloud lock-in + breach risk)

5. **ČSN EN 50131 Grade 2+ minimum** — pro insurance reduction qualification

6. **Network segmentation povinné** — IoT VLAN separation chrání main network

7. **Distinct from /energeticka-instalace (FVE) + /vecna-bremena + /predkupni-pravo** — pro smart home použijte /smart-home engine

**5 chyb:**

1. **Skip GDPR consent** = ÚOOÚ fines do 10M Kč (nebo dle čl. 83 GDPR až 20M EUR)

2. **Default passwords** = trivial cybersecurity breach (~40 % installations vulnerable)

3. **No network segmentation** = IoT compromise affects main network

4. **Cloud-only architecture** = vendor lock-in + breach risk + offline failure

5. **Black-box AI bez Jistybyt engine** = no transparency about 5 SmartHomeType + insurance + risk + ČSN compliance
