Parse select entities as string to prevent 'invalid option for select' error

[dvandonkelaar]

Home Assistant logs an error in the created select entity for the Eurotronic SPZB0001 thermostat.

Logger: homeassistant.components.mqtt.select
Source: components/mqtt/select.py:133
Integration: MQTT (documentation, issues)
First occurred: 21:59:16 (11 occurrences)
Last logged: 22:12:14

Invalid option for select.thermostat_eurotronic_trv_mode: '2' (valid options: [1, 2])

The issue is resolved by publishing stringed options to the config topic.

"options": [
  "1",
  "2"
]

Home Assistant is parsing the select options as strings, so setting the available options as a string could resolve the issue.
The only problem right now is it only works for setting the option to 1. Setting the option to 2 does not work with the manually added config as above.
My knowledge about JavaScript/Zigbee2MQTT is limited, maybe someone with a little more experience could help out?

I'm wondering if this should be solved in Zigbee2MQTT, I don't see why a number values are not valid. If I look at the docs https://www.home-assistant.io/integrations/select.mqtt/ -> options I don't see any requirements on it either.

@emontnemery is this something that can be fixed @ HA?

@Koenkk Select options are strings, as per specification.

@frenck thanks for the clarification.

@dvandonkelaar thanks for the fix! 😄

Thanks! Just tested it and it works as it should.
