Possibility to send followme temp data from wireless

[tabascoz]

Hi there, thank you once more for this awesome work!

I have an issue which is (with a big house) every now and them, someone just turns off the ACs by using the remote controls. And with that, the IRs stops to send follow me current temperature.

For the heat mode, it is a must to have follow me. As i understand there's some design/engineering flaw that the AC does not perform well without that, with its internal temp showing a positive offset of more than 6 degrees C. Values are sometimes superior to the setpoint temp. I am suspecting is because of the physical location of temp probe sensor.. This doesn't happen with cool mode.

So to me the follow me mode is more than an fancy thing - it gives me reliability to turn on the ACs from remote and know the'll do what i want.

I was thinking that It might be possible to send to the unit the follow-me temp to AC from the dongle, based for ex. in an external temp sensor. I've come across this esphome/issues#5862 (comment). Have you dig into this?

I'll take a look at the referenced link and see if I can glean anything new. My initial impression is that the IR protocol and UART protocol aren't nearly as identical as the poster believes.

Are you using the OEM remote or have you constructed something based on ESPHome? With an ESPHome IR blaster I would think this problem could be solved with some clever automation

In the last few days I have also been working on sending a temperature value to the system using an IR blaster.
However, my goal was different. I wanted to send a fixed value to the system in order to be able to better control the system performance manually.

How far have I come? At least it works to trick the system into thinking it has a fixed room temperature.

All you need is an HA supported IR blaster. I have this device, which even has sensors for humidity and room temperature.

The device can be integrated into HA via Local Tuya and the IR remote control can then also be trained and used under “Actions”.
I learned various commands, including the LED button. It works.
I was also able to learn FollowMe. Place the original remote control in front of it, press "Learn" several times for 60 seconds until the tick turns green. (The original remote control only sends the signal every 2-3 minutes)

Now I can switch off the original remote control and the IR blaster automatically sends a temperature of 20°C to the air conditioning every 2 minutes.

The goal of the query in this issue has probably already been achieved with this IR blaster. The opener can see the current room temperature even in remote locations and can switch his system as desired.

But now the unsolved problem that would perfect the whole thing. And therefore the remote control is unnecessary.

• HA reads the actual temperature from the sensor in the IR blaster, translates it into an IR signal and sends the currently measured room temperature to the air conditioning every 2 minutes.
  Can we get this to work?
  The advantage over the remote control is that you get the room temperature with one decimal place and, as I see it, the air conditioning system can even evaluate this decimal place internally for its control.
