IoT Message

Sending SMS from your IoT devices has gotten harder. It does not need to be.

IoT Message turns what your devices report into text message alerts, sent to the people responsible for each device. Currently supporting Hologram devices.

Free includes 10 alerts a month to your own verified number. No card needed.

How it works

  1. Connect Hologram

    Save your Hologram API key, stored encrypted. IoT Message reads your devices and the messages they send, about once a minute, and can also take Hologram alert webhooks.

  2. Write triggers

    Choose which events matter: a tag, a threshold, a value that appears. Test a trigger against your recent events before it sends anything.

  3. People get the text

    Each alert goes to the recipients you associate with that device, using a message template that fills in the device name, the time, and the values you pick.

Built for alerts people act on

Per-device recipientsAssociate people with specific devices or tags, so one account can serve many sites or customers. Recipients can sign themselves up with a link you share.
CooldownsA device that flaps sends one alert, not fifty. Suppressed alerts are still recorded.
Long alerts, one messageAlerts too long for two text segments go out as a single MMS, so every alert is one message on your bill.
Delivery you can seeEvery alert shows delivered, failed, or why it was not sent, including recipients who replied STOP.
Hard monthly limitYour plan's cap is never exceeded, and you are emailed at 80%.

Start with your own phone

The Free plan sends alerts to your verified mobile number. Upgrade when others need them too.
