| Honeywell T6 Z-Wave thermostat | Works Local | Used as single-mode thermostat with keep-between setup; example documentedSaved copyThis isn't actually an "issue". Just documenting an example use-case that might be helpful for others or for some LLM to find. I have a Honeywell T6 ZWave thermostat. It shows up in HA as a "single-mode" thermostat. IDK if "single-mode" is an official term, but basically I just mean you can only set one mode at a time. I was coming from a Nest thermostat and really wanted to replicate the "Keep Between" functionality. I also really wanted it to show up nicely in Apple Home via the Homekit Bridge integration. So I found this ha-dual-smart-thermostat extension. It was pretty easy to get the … Excerpt saved from GitHub on 2026-10-23. | Issue #432 · 2025-09 | |
| Heat pump thermostat (summer mode) | Partly works | Partly in Home Shows cooling but mode dropdown does not reflect swapped heat/cool modes | HVAC modes swap heat/cool with sensor; Apple Home dropdown not updatedSaved copyHi @metabubble, we investigated this and the mode update is working correctly on our side. When the `heat_pump_cooling` sensor changes state: 1. The heat pump device swaps HEAT↔COOL in `hvac_modes` 2. The climate entity syncs `_attr_hvac_modes` from the device 3. `async_write_ha_state()` is called, publishing the updated modes to HA's state machine You can verify this in the HA UI, the climate card should show the updated modes (Cool/Off instead of Heat/Off) when the cooling sensor switches. If the HA UI shows the correct modes but HomeKit doesn't, the issue is in the HomeKit integration's … Excerpt saved from GitHub on 2026-10-23. | Issue #504 · 2025-12 |
