Error at startup: TypeError: unhashable type: 'set'

[browetd]

I have the following error for each device in Cozytouch when I start Home Assistant (I have used Hacs to install Cozytouch... Not sure if the problem is coming for the code or the integration within Hacs). To set up the platform, I used the method via the integration menu... All entities seem to work correctly... I have uninstalled Cozytouch, restarted HA and reinstall it, restarted HA, same issue. Thanks !

Hello, I have the same issue. Seems to work ... Same Error in 1.1 version or 1.2 version installed within HACS I'm running under raspbian (raspberry PI 4 , 4Go)

Here an extract of the log: 2020-01-16 00:13:21 ERROR (MainThread) [homeassistant.core] Error doing job: Task exception was never retrieved Traceback (most recent call last): File "/srv/homeassistant/lib/python3.7/site-packages/homeassistant/helpers/entity_platform.py", line 333, in _async_a dd_entity device = device_registry.async_get_or_create(**processed_dev_info) File "/srv/homeassistant/lib/python3.7/site-packages/homeassistant/helpers/device_registry.py", line 133, in async_ge t_or_create via = self.async_get_device({via_device}, set()) TypeError: unhashable type: 'set'

I run into this as well and found that it caused the presence sensor to be ignored (HACS install). After the fix (in PR) they are discovered without problems.

Now instead of having this for each radiator I have, I only have once.

Still have it in 0.109.1 (one for binary_sensor and one for climate) see below. I do not have any binary _sensor nor climate entity... Just sensors (two per radiator...One for temperature and one for electricity) Any solution ? Thanks

Hello, It seems there arelot of activities on new development for the cozytouch integration https://github.com/Cyr-ius/hass-cozytouch. Idem --> the discovery of sensors seems to be more stable , but I've lost all the climate :-(

I've not seen how to post issues Philippe

Hi, I think it is not possible to post issue on https://github.com/Cyr-ius/hass-cozytouch. I have seen that one of the recent commit is similar to one of my pull requests (unique-id for climate). but the part fixing the unhashable type error is not present in master. @Cyr-ius : can you remove the {} arround the via-device definition to fix this issue ?

Sorry, I had not seen your PR

Problem fixed for me with version 1.4.0b: the error message (unhashable) disappeared and the binary sensors + climates are back !!! Nice... Thank you ! But now I have other error messages that I have to investigate... but this one can be closed.
