Why Your Farm Data Should Stay on Your Farm

The case for local-first farm sensor data — no cloud accounts, no monthly subscriptions, no vendor lock-in. Your sensor readings, your storage, your formats, forever.

Every smart-farm product on the market wants your data on their servers. Not because it’s better for you — because it’s better for their recurring revenue model.

Here’s why we built OGLAS to work the other way.

The subscription trap

A typical cloud-connected farm sensor setup:

  • $5–15/month per device for connectivity (SIM plan, API access, “premium features”)
  • Data held hostage — cancel the subscription, lose access to your history
  • Feature tiers — want alerts? That’s the Pro plan. Want more than 90 days of history? Enterprise.
  • End-of-life risk — company gets acquired or shuts down, your hardware is e-waste

Over a ten-year farm deployment — and farm infrastructure should last a decade — the subscription costs dwarf the hardware by an order of magnitude.

What “local data” actually means

With OGLAS, the hub logs every sensor reading to local storage — flash, SD card, a NAS, your choice. The format is plain text and easily-parsed binary. There’s no mandatory OGLAS cloud account — local is the default, and nothing is pushed off your site unless you choose it.

This means:

  • No subscription. Buy the hardware, run it, done.
  • No lock-in. In five years, if you want to move to a different system, your data is in plain formats. You’re not negotiating an export from someone’s API.
  • No account. No login, no password, no app-store dependency.
  • No telemetry. The hub doesn’t phone home. Updates are pulled when you choose.

The trade-off, honestly

You are responsible for your own backups. We can help you set them up — SD card redundancy, rsync to a NAS, whatever suits your setup — but nobody else is going to do it for you. That’s the deal: total control comes with total responsibility for the data.

We think that’s a good deal. If the power goes out, your sensors still talk to your hub. If the internet goes out, your hub still logs. If we disappear as a company, your hardware still works, your data is still yours, and the formats are open and documented.

What about remote access?

“Local” doesn’t mean “can’t access it remotely.” It means the default is local, and remote access is a choice you make:

  • Tailscale or WireGuard into your home network — secure, no open ports
  • A VPS you control running a dashboard that pulls from your hub (or the optional OGLAS Cloud, on your terms)
  • A phone app on the local network when you’re in range

All of these are your infrastructure, on your terms. No third party sits between you and your data.

The industry is starting to notice

The “local-first” movement isn’t just us. From Home Assistant in home automation to ChirpStack in LoRaWAN networks, the pattern is the same: people who run infrastructure on their own property want control over the data that infrastructure generates.

OGLAS is that idea applied to farm sensors.

This is pillar one of Why OGLAS. The other three: no telco dependency, monitoring and alerts, and off-grid power.
