core: Log error in CORE for adding integration to Broadlink SmartPlug

The problem

Since 0.115 - Broadlink SmartPlugs issue log errors -> need to be added via integrations I presume

Attempt 1:

• I fixed the yaml setup of the smartplugs (had to comment the type & friendly_name to pass configuration check)
• The integration discovery found the plug but issued log error on the core
• Switch entity was not created

Attempt 2:

• Removed yaml config completely, after restart try to add integration manually
• The device was recognized with the IP i provided for host but another error was issued on core log
• Switch entity was not created

Environment

• Home Assistant Core release with the issue: 0.115
• Last working Home Assistant Core release (if known): 0.114.4
• Operating environment (OS/Container/Supervised/Core): Hassio (?)
• Integration causing this issue: Broadlink
• Link to integration documentation on our website: https://www.home-assistant.io/integrations/broadlink/

Problem-relevant configuration.yaml

the yaml used on atemp # 1

  - platform: broadlink
    host: '192.168.1.53'
#!secret spmini_coffeemaker_ip
    mac: 'B4:43:0D:B7:87:03'
#    type:  sp2
#    friendly_name: 'Rancilio Coffee Machine'

on second attempt - relevant yaml removed !

Additional information

The device I am trying to add was previously identified as SP2 smart plug in yaml config that worked on 0.114.4 and previously

My router identifies the device as "BroadLink_SPmini-T1-d9-38-dc " incase it helps… - this is definitely NOT and RF/IR type RM of some sort - I have one of those and it was discovered and working properly)
