WanderTherm is a planned 2-tier smart thermostat designed to replace Nest 4th Gen ($279) while delivering a meaningfully better experience: zero cloud required, covert mode + duress code (survivor / undocumented / hostile-state aware), identity-aware defaults, OpenTherm + 24V dumb-thermostat compat in single hardware SKU (move from US to EU without buying a new thermostat), 7-year parts + open STL face plates + published schematics, AHRI 1380 + Energy Star Connected for utility rebate eligibility, Matter 1.3+ over WiFi + HomeKit + Google Home + Alexa + Home Assistant first-class, decision-tree schedule learning that explains itself (NOT opaque ML), Ambassador-assembled, 60/30/10 Community Pool. Standard (price TBD) = ESP32-S3 + Bosch BME688 + TI TMP117 + GoodDisplay 1.54" round e-ink + 4× Omron relays + OpenTherm transceiver (firmware-flag) + saffron LED status arc. Pro (price TBD) = Standard + 4× zone-valve relays + 16-sensor BLE-mesh + LD2420 mmWave presence + zoned-heating algorithm. Both feed the 60/30/10 Community Pool. Comparable competitors require cloud accounts, paywall geofencing, ship microphones in thermostats, and have no identity-aware defaults at all.
