An ESPHome Bluetooth proxy with an OLED climate and status display for Home Assistant.
Windows Manager 1.6.0
What is HA Proxy Panel?
It turns an ESP32 and a small 128x64 OLED into a Bluetooth proxy with a live climate and status display. Control content, rotation, brightness, and OLED Care from Home Assistant, then maintain it with the desktop manager or ESPHome Device Builder.
Climate display
Choose Home Assistant temperature and humidity sources, with climate, single-value, and proxy views.
HA controls
Choose display mode, normal or 180 degree rotation, brightness, and OLED Care without reflashing.
OLED Care
Pixel shifting and a full-panel refresh reduce long-running static patterns.
Wi-Fi status
Check signal, IP, uptime, source, firmware, proxy state, and availability. A QR fallback portal handles first setup.
Update notifications
A blinking indicator and bottom-up tray announce panel and ESPHome updates without covering climate data.
01
Flash, discover, and manage every panel.
HA Proxy Panel Manager 1.6.0 is a standalone Windows app. No Python installation is required, and ESPHome 2026.7.4 is bundled.
HA Proxy Panel Manager for Windows
Windows may show SmartScreen because this community app is not code-signed. Compare its SHA256 with the value on the v1.6.0 release page.
Connect securely
Use Home Assistant OAuth with MFA or a manual token fallback. Tokens and device secrets are encrypted for your Windows account with DPAPI.
Flash and onboard
Detect USB devices, import a saved Windows Wi-Fi profile, download and verify the exact GitHub firmware commit, then follow the phone QR setup when needed.
Discover every panel
Find panels through Home Assistant and mDNS, search the LAN, or connect directly by IP. Switching devices keeps the dashboard stable and readable.
Control live
Change display mode, rotation, brightness, and OLED Care. Run its animation, restart a panel, inspect entities and diagnostics, or prepare new sensor sources.
Update safely
Install verified official firmware over Wi-Fi while preserving identity, sensor sources, display settings, encrypted or legacy API mode, and OTA configuration.
Add to Home Assistant
Transfer the matching API key securely, complete ESPHome discovery, and create protected Device Builder YAML without overwriting an unmanaged project.
