I have been a big fan of Meross gear for years, using it where possible to power my automated home.

Recently though, I received an email from Meross giving me 72 hours to fix an "issue" that my equipment was sending messages to their cloud server at an unaceptable rate.

The email contained no information about which device(s) were creating the problem.

I responded immediately to their "support" team (I use the term jokingly), requesting more details, but they failed to respond in a timely manner, and my cloud service was shut down, causing me to lose access to several critical devices.

I did some searching on the content of the email, and the issue appears to be related to using Home Assistant (I think the most commonly used Home Automation software), so I removed the Meross module from Home Assistant, whilst continuing to converse with Merross "Support" to identify the actual issue so that I could resolve it.

The final email from "Support" was this :

Please double-check your installation to ensure the following: avoid using any APIs or plugins such as Home Assistant, or ensure the cloud access limit is not exceeded (no more than 200 messages per hour, per device).

So, Meross do NOT support Home Assistant (in fact they actively discriminate against it), which makes it a deal breaker for me (and doubtless millions of others).

I will be replacing my Meross equipment with something I can rely on, and encouraging others to do the same.

Very disappointing.
