Product notes
CSA End Product Thermostat 0x0301 Thread. Maker/Amazon.de/Currys: Matter; Apple Home, Google Home, Alexa (Matter controller required). Same radiator-valve form factor class as Eve Thermo — Partial vs whole-home HVAC thermostat expectations.
v0.48 High add. CSA details from WebSearch CSA product synthesis (curl 403); retail Amazon.de + Currys UK verified. Companion to eve-thermo TRV, not a US 24V HVAC wall unit.
How it differs from the type answer
- TRV/radiator valve — Partial fit vs Nest-style whole-home HVAC thermostat columns (same caveat as eve-thermo).
- Zigbee path available when paired to Bosch Controller; default Matter mode for third-party fabrics.
- EU-focused retail this pass (Amazon.de / Currys); no US store verified.
