IoT Integration & Middleware

(Sensorberg and Spaceti are cross-listed; their vendor detail lives in CAT-01 and CAT-03 respectively.)

Category note: Two layers share this category. Layer 1 — SaaS automation glue (Zapier, Make, n8n): 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: connecting physical hardware (doors, sensors, HVAC) to software — the territory of Sensorberg (CAT-01) and Spaceti (CAT-03), 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 — CAT-11); sensors feed in via MQTT (CAT-02); and the AI agents of CAT-23 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 — 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-23) — 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-02 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-25 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
