Need to downgrade it as v7 is not working with MCOHome and seems to have stability issue too.
Thank you.
When a firmware has been released as stable, like v7 has, you can’t downgrade.
@Rico I will push a fix for the MCOhome issue this morning.
I was anticipating that Athom would have released the final solution as an update within Homey v7 already (will not happen this week)…
Thank you. Really appreciate your time on this.
Noted. Next time will be more careful on update. 
@Rico should be fixed (error out of Homey v7 core contained) in the 1.4.1 version of the MCOHome app
