RY3T NOVA

A 3 kW bitcoin miner on castors from Swiss start-up RY3T, built to use up rooftop solar surplus: a solar or home-automation controller sets its power, and up to three units stack to 9 kW. RY3T quotes 110 TH/s per unit and sells it on mining yield; the warm air is a side effect that can dry laundry in a garage or utility room, and in summer the unit can be rolled outdoors. A 100-unit pre-sale at CHF 1,499 (CHF 1,699 afterwards) with a refundable CHF 500 deposit opened in June 2026; delivery was planned from August 2026 with no binding date, and none has been reported.

*What a pool would pay on average at today's difficulty, block reward and bitcoin price, before pool fees. Solo miners usually earn nothing, and very rarely a whole block. A plain electric heater turns the same electricity into the same heat, so the mining income is what makes the difference.

Payback is how long the bitcoin a device earns takes to add up to its price. It leaves out electricity, which buys the heat: compare earnings per kWh with your electricity price to see whether mining alone covers it. It uses the average of the last 3 months, to 12 Nov 2026: bitcoin at $79,558, 969 EH/s on the network and 3.15 BTC a block, less a 2% pool fee, for the hours you set. It cuts the block subsidy in half at each halving, the next around Apr 2028, and otherwise assumes those carry on unchanged, which they won't. Income at today's difficulty and price is about 17% below that average. Hashrate usually rises, though miners that stop paying after a halving may switch off, which leaves more for the rest. How we work it out.

Sources and data notes

Not yet confirmed from the maker's own documents: production status (pre-sale opened in June 2026; RY3T planned series production and delivery from August 2026 with no binding date; on 2026-11-05 the site still says 'from August 2026', its news stops at a 14 July 2026 prototype 'ready for the next tests', the 256 Foundation called it 'in development' on 14 Aug 2026, and no delivery has been reported); launch date (June 2026 is when the pre-sale opened: technikblog.ch says it started on 3 June 2026, the date of the terms, while RY3T's 11 June press release says it started 'this week'; no unit has shipped); hashrate (110 TH/s is RY3T's spec-table figure; no measured figure for a production unit; the 256 Foundation's screenshot of a test unit showed 74.4 TH/s at 2.43 kW); efficiency (not published; 3 kW and 110 TH/s imply about 27 J/TH); input voltage (only 'CEE 16A' is given; the product image shows a red CEE plug, which usually means 400 V three-phase, but RY3T does not say); frequency; dimensions (only a 0.5 m² footprint is published; RY3T says dimensions are still to be finalised); weight; noise (site and FAQ say under 55 dB, provisional, and the perceived level depends on the room; the June 2026 press gave under 50 dB); operating temperature (only 'indoor or sheltered outdoor' placement is given); area heated (RY3T makes no heated-area or heat-output claim); cooling (not stated in words; the Modbus map reports fans and fan faults and the images show mesh side vents); colours (images show a black or anthracite case; no colour options listed); SKU (none published; the page's tracking code uses the ID 'RY3T-NOVA'); where it's made (RY3T says 'Made in: Switzerland' and showed the prototype assembled in Switzerland; the Modbus model codes point to Bitmain S19j Pro and S19k Pro hashboards, so this means Swiss assembly); features (Mujina firmware and the stock Bitmain control board come from the 256 Foundation, not RY3T's pages; MQTT is 'planned' in RY3T's integration docs although the sales page lists it; the integration docs describe gradual ramping of about 500-3,000 W per miner rather than 1 kW steps); store listings price (the terms call the pre-sale price 'voraussichtlich' and say prices are finalised at launch); store listings taxIncluded (site, terms and the Moneycab release say incl. VAT; technikblog.ch on 3 June 2026 said excl. VAT); store listings shipsFrom (RY3T in Wil says it delivers directly and takes returns in Wil; the dispatch point is not stated).
