Built for homeowners, not home servers
ProbeHarbor is for live probe sensors, freeze and flood/leak alerts, and optional SMS, without running your own infrastructure. Plan limits and the Free/Member/Pro/Portfolio matrix live on Pricing; this page compares ProbeHarbor to other approaches.
Detailed comparisons
Side-by-side guides for common alternatives: ops burden, alerts, and when each option fits.
- ProbeHarbor vs DIY MQTT
DIY MQTT is powerful if you enjoy running brokers, dashboards, and alert scripts. ProbeHarbor is the same outcome, live probes, freeze and leak alerts, history, without babysitting the stack at 2 a.m.
- ProbeHarbor vs Govee
Govee, and consumer hubs like SmartThings: are great for cheap room sensors and a polished phone app. ProbeHarbor is built for freeze and leak workflows in garages, workshops, attics, and shops: your own ESP probes, household alerts, and history you can export.
- ProbeHarbor vs Tempest
Tempest shines at yard weather: wind, rain, outdoor temp. Pipe freeze risk lives indoors. ProbeHarbor watches the garage, crawlspace, or shop where the plumbing is.
- ProbeHarbor vs Nest Thermostat
Nest is excellent at running your HVAC and reporting the temperature where it (or a Nest Temperature Sensor) is installed -- almost never the garage, crawlspace, or shop where pipes actually freeze. ProbeHarbor watches that space directly, and if you connect your Nest account, pulls its reading and heating status into every freeze alert for context.
- ProbeHarbor vs Ecobee Thermostat
Ecobee is excellent at running your HVAC and reporting the temperature where it (or an Ecobee SmartSensor) is installed -- almost never the garage, crawlspace, or shop where pipes actually freeze. ProbeHarbor watches that space directly, and if you connect your Ecobee account, pulls its reading and heating status into every freeze alert for context.
- ProbeHarbor vs TempStick
Temp Stick is the easier choice for one or two spaces: a finished battery sensor, no subscription, and free text, email, and app alerts. ProbeHarbor is cheaper per sensor and more flexible (several probes, leak contacts, Home Assistant), but you build the sensor and SMS needs Pro.
- ProbeHarbor vs YoLink
YoLink is the easier and often cheaper choice for finished sensors: a hub and two battery sensors cost $59.99 and alert by push, email, and SMS. ProbeHarbor fits if you want a probe taped to the pipe, no hub, your own hardware, or readings in an open system.
- ProbeHarbor vs SensorPush
SensorPush makes small, accurate Bluetooth sensors with a polished app and no monthly fee, but alerts away from home need the $99.95 Wi‑Fi gateway. ProbeHarbor probes report over Wi‑Fi directly and can sit on the pipe; you build them, and SMS needs Pro.
- ProbeHarbor vs Shelly H&T
The Shelly H&T Gen3 is a tidy $40.99 Wi‑Fi room sensor with a display, MQTT, and webhooks. Shelly rates it for 32°F to 105°F, though, which rules it out for spaces that actually freeze. ProbeHarbor uses a probe rated far below freezing, mounted on the pipe.
SmartThings can add ProbeHarbor sensors via the Matter bridge path (no Cloud-to-Cloud app). Consumer pods still sit with Govee below: Govee guide.
Complementary, not a rival: keep HA on the LAN and use ProbeHarbor for household freeze and leak SMS, history, and off-site alerts. Official HACS integration + MQTT dual-run notes on the Home Assistant page , and see vs DIY MQTT if you’re weighing a full self-hosted stack.
ProbeHarbor vs alternatives
| Capability | ProbeHarbor | DIY script + cron | Govee / SmartThings |
|---|---|---|---|
| Time to freeze (this space) | Forecast-backed clock + remaining-hours alert | You write the model | Threshold only |
| Freeze alerts (email/SMS/push) | Built-in, per-household | You wire Twilio + cron | App push; SMS extra or absent |
| ESP/Arduino push ingest | One-time device key | Custom endpoint | Govee pods / SmartThings devices |
| History & CSV export | On paid plans | Self-hosted DB | Subscription tiers |
| Share links & Grafana | 1 family live link; Pro adds history/metrics | Manual setup | Rare on consumer apps |
| Home Assistant (HACS) | Official integration (share link) | REST sensors + webhooks | Varies by vendor |
| Household multi-user | Free | N/A | Family sharing is awkward |
| Hosting & uptime ops | Cloudflare edge; public status | You own the VPS / cron | Vendor cloud (opaque) |
Who it's for
- Free, one property, live charts, email/chat alerts, and one family live share link while you evaluate.
- Member. CSV history and more devices through a cold season.
- Pro. SMS, Nest/Ecobee house context, unlimited share scopes, Home Assistant (HACS), claims pack, and webhooks when someone needs to wake up at 2 a.m. Free already includes one family live link. See the HTTP API for ingest and metrics.
- Portfolio, for larger multi-property ops past Pro’s property ceiling, with property-manager logins. Details on Pricing and property management.

Frequently asked questions
How is ProbeHarbor different from a DIY script?
ProbeHarbor hosts ingest, history, households, and multi-channel freeze and leak alerts for you. A DIY cron script requires you to run servers, databases, Twilio wiring, and uptime yourself.
How does ProbeHarbor compare to Govee or SmartThings?
Govee and SmartThings are general consumer/smart-home apps. ProbeHarbor is purpose-built for garages, workshops, attics, crawlspaces, and shops: ESP/Arduino or JSON ingest, freeze workflows, air quality, doors, leaks, energy, and CSV history, rather than a catch-all device dashboard.
Do I need a public IP for my Arduino?
No for push ingest: the device POSTs outbound to ProbeHarbor. Pull feeds need a reachable HTTPS JSON URL if you use that path instead.
Can I keep Home Assistant or MQTT and still use ProbeHarbor?
Yes. Install the official HACS integration (github.com/doodersrage/thermaltrace-home-assistant) for automatic entities from a share link, or keep MQTT on your LAN and mirror with POST /api/ingest/mqtt. Many people dual-run: HA locally, ProbeHarbor for household freeze and leak SMS and history. See probeharbor.dev/integrations/home-assistant.
Why does ProbeHarbor require an account?
ProbeHarbor is hosted so you do not run databases or SMS wiring yourself. A free account (no credit card) attaches your ingest key to your household. You can still dual-run with Home Assistant or MQTT on the LAN. ProbeHarbor is the off-site alerts and history layer.
Do I need to keep a home server online?
No. ProbeHarbor runs on Cloudflare’s edge; your probes only need outbound HTTPS (push) or a reachable pull URL. Live service health is at probeharbor.dev/system-status.
I already have Govee or a Tempest: do I still need this?
Govee is a consumer room sensor; Tempest is outdoor weather. ProbeHarbor watches probe curves in garages, workshops, attics, crawlspaces, and shops on hardware you control. They can coexist: see the Govee and Tempest comparison pages for when each tool is the better fit.
