Running FOSS miner firmware (mujina) on two FOSS hashboards (bitaxes) with our own FOSS mining pool (hydrapool).
Raspberry pi with Debian OS is acting as the “control board”.

Happy New Year Heatpunks!
Just put together a full walkthrough tutorial for our Hashrate Heating savings calculators from @Exergy
Our 2026 roadmap is epic. Stay tuned for hashrate solar calculators and full fledged ROI estimates, unique to your heating load profile.
Ever wonder if mining bitcoin could be a cheaper way to heat your house? Unsure if it makes sense with your electric and fuel rates? Curious how different miners stack up?
Check out our first @Exergy vibe-coded web app for hashrate heating calcs. Link and source below
Glad to see Hashrate Heating has made the ASHRAE newsletter for industry news!
"Americans Are Heating Their Homes with Bitcoin This Winter ... someday its use as a [heat] source within homes and buildings will be much more widespread"
Cloud flare outage experience today:
- At Home: Couldn't send a command from phone to turn off the furnace. (Ecobee talks to remote server).
- At Exergy Office: Home assistant app on our phone sends command directly to local node, passes command over local API to our thermostat (Venstar) & miners.
Highly recommend attending the @start9labs service packaging office hours with Matt and team.
Today he walked us through the how-to with a live Home Assistant packaging demo.
Now on 0.4.0 Alpha 12.

It was a pleasure chatting with Brandon from Sovreign about what we’re building at @Exergy_LLC
We dive deep into our process for heating homes with Hashrate. Give it a listen!
Thanks to @spiralbtc for sending these resources to our bitcoin community hub, @SpaceDenver
We’re going to start a little local competition to see who can get the most businesses accepting freedom money.
Got to chat with Isa and Eco about mining centralization at a dinner last month.
Few weeks later and we have an excellent mini doc to bring people up to speed.
The power of story telling! Great work 🙌
Heatpunk Winter is Coming
Don't know where to start? Get a Heatbit or Canaan Mini 3 space heater.
Feeling savvy? Get an Avalon Q and duct the heat exhaust into your furnace.
Want your miners to respond to your existing thermostats? Check out @Exergy_LLC documentation.
Almost all gas heaters are oversized because they are cheap to add extra head room to. Just burn more gas. Open valve longer.
Hashrate Heat requires proper sizing on the margin to get best bang for buck. Don’t want to buy asic chips you won’t use.
Goal is to optimize mining duty cycle for average heat load so you get most sats.
We do this at @Exergy
Only those who measure hashprice in Dollars/PH care.
Usually those measuring in Cents/TH are immune, aka solo mining, non-KYC stacking, or heating their house.
Note on Node-RED. There are pros and cons here compared to PyASIC /
Node-RED:
Pros)
No service maintenance. If you have the API documentation, you can build anything you want. Don't need to be a developer.
Cons)
More difficult setup process. Not an out-of-the-box setup process.
PyASIC/ASIC.rs:
Pros)
Automates setup. Input miner IP, define power limits. API commands and miner stats are automatically brought in to Home Assistant vis the HASS miner HACS integration.
Cons)
Requires continuous maintenance to add new miners. Does not always include all API variables for every miner command. Needs active development for each new "hashrate heating model".
Hashrate growth should replace GDP.
It’s a metric of the human capacity to harness untapped energy, build capacity, eliminate waste and maximize efficiency.
The sovereign smart home means controlling your internet connected devices locally, without big tech overlords watching every move.
Hashrate heat is now sovereign smart home infrastructure.
Follow Dylan's docs for @Exergy_LLC to command the Canaan Mini 3 from Home Assistant!
