Water tanks

Water tanks — fresh + grey water telemetry + pump runtime + leak detection + freeze-risk monitoring for vans — is the vendor-neutral surface that turns "is the fresh tank still full enough to last the night?" into a dashboard tile + a push notification + a mode-aware automation.

• SeeLevel / Garnet tank sensor ($80–$200)
• 12 V solenoid valve ($25–$60)
