A precision ToF laser sensor that measures your brine tank salt level in real‑time — no floats, no guesswork. Connects directly to your home WiFi.
Coming Soon
Non-invasive optical turbidity & sediment monitor engineered for standard 133 mm (5.25" OD) clear whole-house filter sumps (compatible with standard 10" and 20" clear canister sumps). Tracks filter saturation from 0% to 100% in real-time through the canister wall — zero plumbing changes required.

Stay in the LoopConnects straight to your home WiFi. No proprietary bridge, no subscription, no cloud lock‑in. Your data stays local.
ESPHome firmware means BrinePulse is auto-discovered by Home Assistant. All entities available instantly — sensors, switches, buttons.
The BrinePulse app gives you a clean dashboard, push alerts when salt is low, and calibration tools — all without needing Home Assistant.
Time-of-Flight sensor. No floats, no electrodes. A focused laser beam reads tank depth to within millimeters.
Mount the sensor, power via USB-C, and use the app to connect to WiFi. No electrician, no drilling, no configuration files.
ESPHome firmware is fully open. Flash your own code, add custom automations, or integrate with any MQTT-compatible system.
New firmware is delivered wirelessly. Install from the BrinePulse app, your Home Assistant dashboard, or directly from the device's built-in web page (open your device IP in a browser). No cables, no disassembly.
The BrinePulse app shows live salt levels, salt usage trends, and sends push notifications before you ever run out of salt.
BrinePulse runs ESPHome firmware — the gold standard for HA integration. Every sensor, switch, and button appears in Home Assistant automatically. Build automations, dashboards, and alerts without writing a line of code.
Download the firmware binary to manually update via the device's built-in web interface or Home Assistant ESPHome add-on.

BrineLink is an independent hardware company based in Houston, TX — engineering smart home sensors that are open, reliable, and actually useful.
We started BrineLink because we were tired of "smart home" devices that require proprietary hubs, monthly fees, or stop working when a company shuts down their server.
BrinePulse — our first product — uses ESPHome firmware and standard WiFi. It works with Home Assistant, with our free app, or completely standalone via its web interface. No account required to use it locally.
We're building a full lineup of IoT sensors for the home systems people actually care about but can't see. Salt tanks, water quality, sump pumps, HVAC filters. Stay tuned.
BrinePulse is in stock and ships free. Setup takes under 2 minutes.
