Integration reports extremely high temperatures from sensors after values cross 32F/0C
Describe the bug I am experiencing an odd behavior related to how temperature readings from my Tosot (Gree) mini-split unit get reported around freezing. Every time the outdoor temp sensor on the compressor unit crosses the threshold of freezing (32F or 0C), the value of all temperature sensors (indoor and outdoor) jump wildly high. For example, the indoor temperature reading will jump from 66F to 138F, and the outdoor temperature will jump from 32F to 104F. This can be seen in the screenshots below. The sensor values are "reset" back to their correct value by either reloading the Gree integration, or restarting Home Assistant.
To Reproduce With Gree Climate Component installed, observe the reported room temperature and outdoor temperature as the outdoor temperature crosses the freezing threshold.
Configuration Configured via UI, sensors and features auto-discovered, with API V2. US_Imperial temperature units.
Expected behavior Crossing of freezing temperature threshold should not affect how temperature values are reported.
Screenshots
I wasn't able to get a screenshot with the pop-up showing the actual transition values, but trust me when I say that the exact moment that reported temperatures spike aligns with the exact moment that the outside temperature hits the value of 32F.
Platform:
- OS: Home Assistant OS 16.3 (as a VM) - Core 25.11.3
- Browser: Firefox
- Version: Gree Climate Component 3.3.2
Additional context I stumbled on a similar issue reported last year with default built-in HA Gree integration, but it doesn't appear to have been resolved because the opportunity to reproduce the issue passed. The link is listed below:
