IoT Integration & Middleware

(Sensorberg and Spaceti are cross-listed; their vendor detail lives in CAT-01 and CAT-05 respectively.)

Category note: Two layers share this category. Layer 1: SaaS automation glue (Zapier, Make, n8n) is the connective tissue when your platform lacks a native integration (new member in the coworking OS → CRM record + Slack welcome + onboarding email; Tally form → tour calendar; marketplace booking → notification). The economics decide the tool: Zapier prices per task and gets expensive at volume, Make prices per operation at roughly a tenth of the cost with a steeper learning curve, and n8n self-hosted removes usage pricing entirely for technical operators. Enterprise iPaaS (Workato, Boomi, MuleSoft) exists above this tier but belongs to corporate IT estates, not operator stacks. Layer 2: building middleware connects physical hardware (doors, sensors, HVAC) to software. This is the territory of Sensorberg (CAT-01) and Spaceti (CAT-05), plus the open-source pair below (Node-RED, Home Assistant) for operators comfortable running their own automation on a Raspberry Pi. The honest caveat on everything self-hosted here: you become the maintainer (updates, backups, breakage), which is a real cost the subscription tools price in. Your platform's own API is the foundation of both layers (Nexudus and OfficeRnD expose full APIs; see CAT-30); sensors feed in via MQTT (CAT-04); and the AI agents of CAT-43 increasingly ride exactly these rails.

Vendor Detail

Zapier

• Origin: United States (San Francisco)
• Markets served: Global
• Segment: All
• Notes: The default automation glue and the largest connector library in existence: 8,000+ apps, including every coworking platform with a public API plus the whole surrounding stack (CRMs, forms, sheets, Slack, accounting). Its virtue is accessibility: linear trigger-action Zaps that non-technical community managers genuinely build themselves. Its cost curve is the caveat: per-task pricing means a busy multi-location operator's automations (every booking, every invoice, every form) consume tasks fast, and monthly bills climb accordingly, which is the point at which operators typically migrate workloads to Make or n8n.
• Website: zapier.com
• Pricing model: Free (~100 tasks/mo); paid tiers from ~$20–30/mo scaling by task volume (annual billing cheaper; current tiers unconfirmed).
• Key integrations: 8,000+ apps; webhooks; coworking platforms (Nexudus, OfficeRnD, Cobot, Optix via API/native).
• Compliance / certs: SOC 2 Type II, GDPR; SSO on enterprise tiers.
• Research status: Researched

Make (Integromat)

• Origin: Czech Republic (Prague)
• Markets served: Global
• Segment: All
• Notes: The price-performance pick: a visual canvas where scenarios branch, iterate and transform data (genuinely more powerful than Zapier's linear model), priced per operation at roughly a tenth of equivalent Zapier task costs (a generous free tier, then entry plans around $9–11/mo for 10,000 ops). The trade is a steeper learning curve; the payoff is that complex multi-step operator workflows (booking → invoice → accounting → notification chains) stay affordable at volume. The standard recommendation: prototype in Zapier if you must, run production in Make.
• Website: make.com
• Pricing model: Free (~1,000 ops/mo); Core from ~$9–11/mo (10k ops), scaling by operations (annual billing; current tiers unconfirmed).
• Key integrations: 2,000+ apps; HTTP/webhooks module reaches any API; coworking platforms via API.
• Compliance / certs: SOC 2 Type II, ISO 27001, GDPR (EU-based).
• Research status: Researched

n8n

• Origin: Germany (Berlin)
• Markets served: Global
• Segment: SMB-Mid
• Notes: The open-source entry in the automation layer, continuing the wiki's thread (Nadine, Xibo, Discourse, Odoo, Metabase): a node-based workflow tool you can self-host free under its fair-code license (removing usage-based pricing entirely) or run on n8n Cloud from around €20–24/mo. Two things distinguish it beyond price: workflows can drop into real code (JavaScript/Python nodes) when no-code runs out, and its AI-agent nodes have made it the default rails for the self-hosted AI automation wave (CAT-43): LLM steps, RAG lookups and agent tool-use inside ordinary workflows. For operators with technical capacity, the ceiling-free option; for everyone else, the maintenance caveat in the category note applies double.
• Website: n8n.io
• Pricing model: Self-hosted free (fair-code license); n8n Cloud from ~€20–24/mo by executions (current tiers unconfirmed).
• Key integrations: 400+ nodes + generic HTTP; AI/LLM nodes (OpenAI, Anthropic, local models); webhooks; databases.
• Compliance / certs: Self-hosted = your controls; cloud SOC 2 (verify current); GDPR (EU).
• Research status: Researched

Node-RED

• Origin: Open source (OpenJS Foundation; originally IBM)
• Markets served: Global
• Segment: SMB
• Notes: The hardware-side counterpart to the SaaS glue above: a flow-based programming tool (literally wiring nodes together in a browser) built for connecting devices, MQTT streams, APIs and dashboards, and light enough to run on a Raspberry Pi in the comms cupboard. In coworking practice it's how technical operators wire CAT-04 sensors into dashboards, trigger lights or signage from occupancy events, and bridge building hardware to webhooks without vendor middleware. Free and battle-hardened (it underpins countless industrial deployments); entirely DIY in setup and upkeep.
• Website: nodered.org
• Pricing model: Free, open source (Apache 2.0); managed hosting via third parties (e.g. FlowFuse) optional.
• Key integrations: MQTT (native), HTTP/webhooks, serial/GPIO, dashboards; thousands of community nodes.
• Compliance / certs: Self-hosted = your controls.
• Research status: Researched

Home Assistant

• Origin: Open source (Open Home Foundation)
• Markets served: Global
• Segment: SMB
• Notes: The world's largest open-source home-automation platform and, quietly, a real small-coworking tool: operators run it on a Raspberry Pi or mini-PC as local-first smart-building control, automating lights, IR-controlled air conditioning, plugs, schedules and presence-based scenes across thousands of supported device integrations, with no cloud dependency and no per-device fees. The honest framing: it's consumer-grade governance (no SLAs, no vendor), best suited to single-location spaces with a tinkerer on the team, the CAT-44 spirit applied to the building itself. The optional Home Assistant Cloud (Nabu Casa, ~$6.50/mo) funds development and adds remote access.
• Website: home-assistant.io
• Pricing model: Free, open source; optional Nabu Casa cloud ~$6.50/mo; hardware (Pi/mini-PC) self-supplied.
• Key integrations: Thousands of device integrations (Zigbee, Z-Wave, WiFi, MQTT); Node-RED add-on; webhooks/API.
• Compliance / certs: Local-first (data stays on-prem); self-hosted = your controls.
• Research status: Researched
