Overview
LoopString supports multi-user access to your devices. You can invite colleagues, contractors, or operators to collaborate on a device without sharing your account credentials. Each person gets their own login and is assigned a role that controls exactly what they can see and do.
Team access is available on the Business tier and above. If you are on a lower plan, you can still use LoopString as a single user, but the team management features will not be available.
How to Invite a Team Member
To add someone to your device, open the device's Settings page and navigate to the Team Members section.
Enter the person's email address and select the role you want to assign them, then send the invite. LoopString will send them an email with a link to accept. The invite link is valid for 7 days. If they do not accept within that window, you can cancel the old invite and send a new one.
Once they accept, they will appear in your Team Members list with their name, email address, and assigned role shown. The person must have a LoopString account — or create one — before they can accept the invite.
You can remove a team member at any time by clicking the remove button next to their name in the Team Members list. Their access is revoked immediately.
Roles and What They Can Do
LoopString uses three roles. Choose the role that matches what the person actually needs to do. It is always better to start with a more restricted role and expand access later if needed.
Viewer
A Viewer can open the dashboard and see live sensor readings, charts, alert history, and device status. They cannot change anything — no actuator control, no setpoint adjustments, no configuration changes, and no access to billing or team settings.
Viewers are appropriate for stakeholders who need to monitor conditions without operating the system. Examples: a quality manager reviewing a temperature log, or a remote investor checking in on a facility.
Operator
An Operator can do everything a Viewer can, plus they can actively operate the system. This includes toggling actuators on and off, adjusting setpoints, and putting sensors into Live Meter mode for higher-frequency readings.
Operators cannot deploy new flows to the device, edit the system configuration, manage other team members, or access billing. Their access is limited to runtime operation of a system that has already been set up.
Operators are the right choice for staff who run day-to-day operations: a technician on a production line, a grower managing a growing environment, or a facilities operator controlling HVAC.
Admin
An Admin has full access. In addition to everything Operators can do, Admins can deploy flows using the Configurator, edit device configuration, manage team members (invite and remove), and access billing settings.
Assign the Admin role sparingly. Anyone with Admin access can change the system configuration and invite other users. Typically, only the primary engineer or manager responsible for the system should be an Admin.
Note: The account owner who created the device always retains full access, even if no explicit team role is set for them.
Collaboration Features
Beyond access control, LoopString includes features designed for teams working together on the same device.
Alert Comments
When an alert fires — for example, a temperature threshold breach — team members can leave comments directly on the alert event. This keeps investigation notes, root-cause findings, and resolution steps attached to the alert record rather than scattered across email or chat.
To comment on an alert, open the Alert Inbox, select the alert event, and type your comment. Comments are visible to all team members with access to the device. Threaded replies are supported so discussions stay organized.
Device Notes
Device Notes are a shared scratchpad for your team. Any team member can add notes that are visible to everyone with device access. Notes can be pinned to keep important information at the top.
Notes are useful for things like maintenance logs, calibration records, shift handover information, or operational reminders. You can optionally attach a note to a specific sensor or actuator so the context is clear.
To add a note, go to the device's Notes section in Settings. You can edit or delete your own notes at any time.
Presence Indicators
When multiple team members have the dashboard open at the same time, small avatar icons appear at the top of the dashboard showing who else is currently viewing. This is useful in operations centers or during incident response, so you know at a glance whether a colleague is already monitoring the situation.
Presence indicators update in real time. If someone closes the tab or loses their connection, their indicator disappears automatically within a few seconds. Your own avatar is not shown to yourself — you only see other people who are currently on the dashboard.
Troubleshooting
The person I invited never received the email
First, ask them to check their spam or junk folder. Invite emails come from the LoopString no-reply address and are occasionally filtered. If the email is not there, cancel the pending invite in the Team Members panel and send a new one. Double-check that the email address is spelled correctly before resending.
The invite link says it has expired
Invite links are valid for 7 days from the time they were sent. If the link has expired, the invited person cannot accept it. Cancel the old invite in your Team Members settings and send a fresh one. The new invite will be valid for another 7 days.
A team member can see the dashboard but cannot control actuators
This usually means they were assigned the Viewer role when they should have been assigned Operator. Only Admins can change roles. Go to the Team Members section in Settings, remove the member, and re-invite them with the correct role. You cannot change a member's role in place — you must remove and re-add them.
I removed a team member but they say they can still log in
Removing a member revokes their device access, not their LoopString account. They will no longer see this device in their account, but their account itself remains active. If you need to revoke their platform access entirely, they would need to delete their own account.
The Team Members section is not visible in Settings
Team access requires the Business tier or higher. If you are on the Starter or Pro tier, the Team Members panel will be hidden. Upgrade your subscription from the Billing section to unlock team management.
Known Issues and Limitations
Role changes take effect immediately for new actions, but a team member who is currently viewing the dashboard may not see the access change until they refresh the page.
There is no role between Operator and Admin. If you need someone to deploy flows but not manage billing, you must assign them Admin — there is no way to grant a subset of Admin permissions. This is a known limitation that may be addressed in a future release.
Invites are per-device, not per-account. If a person needs access to multiple devices, they must be invited to each device separately.
