ProbeHarbor vs DIY MQTT + Node-RED

A Mosquitto broker, Node-RED flows, and a cron job can freeze-alert a garage. The cost is patching, TLS, Twilio, and a Pi that has to stay up. ProbeHarbor is the hosted alerts and history layer: keep MQTT on the LAN if you want, bridge readings over HTTPS, and let household freeze and leak channels live in the cloud.

When to choose which

Choose ProbeHarbor when

  • You want freeze and leak SMS/email/push without wiring Twilio yourself
  • Household members need access without VPN to your Pi
  • You still use ESP/Arduino. HTTPS ingest or MQTT→HTTP bridge

Choose DIY MQTT / Node-RED when

  • You already run a hardened MQTT + Grafana stack and like maintaining it
  • Every automation must stay fully on-LAN with no cloud dependency
  • You need custom industrial protocols ProbeHarbor does not speak

Frequently asked questions

Straight answers for people comparing ProbeHarbor to DIY MQTT / Node-RED.

Can I keep MQTT and still use ProbeHarbor?

Yes. Keep Mosquitto or Home Assistant on your LAN for local automations and bridge selected topics over HTTPS ingest. ProbeHarbor is the off-site freeze/leak alerts and history layer.

Do I need to run Twilio myself?

No. Push and chat channels are hosted on every plan, and SMS on Pro. DIY MQTT usually means wiring Twilio or email yourself and keeping that stack online.
