Support for Thermostat MTS200?

[S474N]

Will be also supported thermostat?

You might try it out. I don't have such device. Feel free to give feedback.

[S474N]

Fiddler is not for iOS :( Is possible to catch communication with another way?

[dehsgr]

You should use fiddle or its alternatives as proxy, not directly on iOS. ;-)

Good point, I'm idiot :D

What information do you need?

[dehsgr]

Which payload is associated with which action? You should provide deeper information what you did and which was the corresponding output. I think guessing would not bring me/us forward. 🤓

[S474N]

Opened Meross app and clicked on thermostat. Do you have some IM? Discord, Messenger,...?

[dehsgr]

you might mail me directly at dehsgr at sign outlook dot sign com.

[S474N]

I thought some instant messages :)

[dehsgr]

Not enough time for IM. :-(

[S474N]

OK, what information do you need to know?

As I wrote - I opened Meross app and then clicked on my thermostat (it's only one accessory from meross).

[dehsgr]

I think you just performed more than one simpe click as you posted 4(!) JSON objecs. As I told here I need more specific information which action is triggering which payload and which configuration information you set.

I don't have such device. So to bring things forward I need any information as detailed as you can - just a step-by-step tutorial...

[S474N]

First is Request and second is Reponse. Same in another post.

[dehsgr]

OK. I see. But you did two different actions. What actions were them? I see Appliance.Control.Thermostat.Mode and Appliance.Control.Thermostat.HoldAction but what do them? You will have to provide much more information.

[S474N]

First is while opening app, second while clicking to thermostat.

[dehsgr]

Ok. And what is the action behind clicking the Thermostat? Should I really ask each detail? 🥶 Common! Tell me a bit more. Screen Shots regarding each payload could be more efficient.

Imagine: I don‘t have such device so it is a totally blackbox for me what is on your site. And you are the one which is asking for supporting this device.

Don‘t forget: I invest my free time here for no return...

[S474N]

I know, but that is main reason, why I wanted IM, because it's faster to response, etc. I will arrange all screens and payloads.

[Cyberbeni]

Hi @dehsgr, there are 2 flows I'm interested in:

1. setting brightness -> this can be done 0-8 from the app, which gets translated to x12.5, so 0-100
2. get current temperature and state for logging (and I guess setting mode/target temperatures didn't require too much plus effort, so I also included those), setting temperature can be done in 0.5C increments

Here is a file with sample requests/responses and some notes: Meross thermostat.md

And some screenshots:

Let me know if you need anything else.

[dehsgr]

Hi @Cyberbeni, thanks for input and the given information. Which devices do support brightness? This is for correctly decision where to place the code. Thanks again.

[Cyberbeni]

I only have the MTS200 (there are 2 variants but the only difference is that one gives power on the output and the other is NO or NC depending on how you wire it), don't know if other devices support brightness.

[S474N]

Hi, sorry for not communicating but I'm sick. I also have the brightness setting in the device menu in the Meross application, but I have no idea what it's for. Unfortunately, I don't have any other Merros devices either.

[Cyberbeni]

The brightness is for the device itself, so if you don't want it to display the current temperature/mode at night, you can set the standby brightness to 0 then set it back to non-0 during the day. (The app doesn't have scheduling for this, that's why I want to do it in node-red)
