Clamp-on "FactoryOps"
Guidewheel vs. Spall
Guidewheel's install avoids the PLC entirely: a clamp-on sensor with no controls work and no IT involved. It is a well-funded, independent company in this category, with energy and carbon reporting built out further than most others here.
Where Guidewheel is strong
- ▸ Installs in as little as a day with non-intrusive sensors and no existing infrastructure required. [Guidewheel, Pricing]
- ▸ Raised a $31 million Series B led by Decarbonization Partners (a partnership between BlackRock and Temasek), with Ecolab and Greycroft also participating. [Businesswire, Guidewheel Series B announcement]
- ▸ Publishes an energy and carbon reporting feature that tracks energy intensity and carbon emissions per machine. [Guidewheel, Reduce Energy Costs]
- ▸ Integrates with ERPs including SAP, Oracle, and Epicor alongside CMMS and BI tools. [Guidewheel, Pricing]
Where Spall differs
- ▸ Reads straight from the controller: Spall reads part counts, cycle times, alarm codes, and machine status directly from the controller, over the machine's own protocols (OPC-UA, Siemens, Allen-Bradley, Omron, Mitsubishi, and more). If a machine has no controller at all, a wired sensor gets the same data.
- ▸ Every finding priced in dollars: Every finding shows a dollar figure, calculated from your own labor, scrap, and energy rates, next to the reading it's based on.
- ▸ Depth past the dashboard: A detailed history of what happened around each event, andon call lights, preventive maintenance, checklists, a logbook, job costing, and energy tracking all come in the product.
- ▸ 30-day pilot: A 30-day pilot includes the hardware, credited against your first invoice if you continue: line pilot $4,500, plant pilot $8,500.
Spall's pricing, published
Connected machines run $200/mo each, dropping to $160 from the 11th machine. Sensed-only machines are $125 flat. A line pilot costs $4,500 and a plant pilot costs $8,500, both 30 days, hardware included, and fully credited against your bill if you continue. You can see the same number on /product without booking a demo.
What connects
Spall connects to 18 kinds of industrial equipment by name, including OPC-UA, Siemens S7, Allen-Bradley, FANUC FOCAS, MTConnect, Omron, Mitsubishi, and LS Electric controls, PLCs, CNCs, and sensors. If a machine has no controller at all, direct 4-20mA and digital-input wiring reaches it too. Check your own machine list against the table at /protocols before you call.
