Products
The hardware and software behind every Exergy building-integrated mining system.
Exergy Products
The control layer that turns a Bitcoin miner into an intelligent heating and solar arbitrage appliance.
CTRL1 Hub
Purpose-built Home Assistant control hub
The CTRL1 is the brain of every Exergy system. It connects your Bitcoin miner to your thermostat, solar inverter, and smart home — pre-loaded with Exergy's open-source integrations out of the box. Raspberry Pi 5 with Zigbee antenna, NVMe SSD, and aluminum case with network display.
Hardware
- Local control only — no cloud, no subscription
- Your data stays on your network
- Supports Zigbee, Z-Wave, and other IoT protocols
- Pre-loaded with Exergy open-source smart home integrations
- Currently included in all Tier 2 and Tier 3 service installs
- Standalone purchase coming soon
Smart Home Integrations
Open-source smart home connectors for Bitcoin miners
Open-source Home Assistant integrations that make a Bitcoin miner behave like a smart thermostat. Reads heat demand, responds to solar generation, and switches operating modes automatically — all running locally on your network.
Supported Platforms
- Free to install via HACS (Home Assistant Community Store)
- Reads heat demand and adjusts miner output automatically
- Responds to solar generation in real time
- Switches operating modes based on your rules
- Works standalone — no CTRL1 required for DIY installs
Integration Types We Support
Every building is different. Exergy supports five integration patterns — one for every existing heat distribution system. We test and validate third-party mining hardware against each.
Smart Zone Heaters
Standalone miners act as space heaters — one per zone. Simple plug-and-play setup for rooms, garages, workshops, or cabins.
In-Duct / Forced Air
Miner sits in your HVAC return duct. Your existing air handler distributes heat throughout the building — no new vents needed.
Hydronic / Radiant
Miner heats a water loop that feeds radiant floors, baseboard radiators, or fan-coil units. Consistent, even heat throughout.
Water, Pool & Spa
Dedicated miner heats pools, hot tubs, domestic hot water, or tank-style water heaters. Heat that was already going to waste.
Excess Solar
Miner acts as a dispatchable load — it ramps up when your solar panels overproduce and scales back when grid demand rises.
Third-Party Mining Hardware
We test, validate, and vet third-party mining systems to confirm compatibility across all five integration types. Hardware changes fast — models, availability, and pricing shift constantly.
What we do
We research the market, buy and test machines, and validate that they work within each integration type before we recommend them to customers. That includes thermal performance, firmware compatibility with Home Assistant, noise levels, and fit for the specific application — space heating, forced air, hydronic, water heating, or solar load absorption.
We also help customers order hardware through us. Pricing changes frequently enough that we don't publish a catalog. Reach out and we'll tell you exactly what we currently recommend, what's in stock, and what it costs for your integration type.
