Hi All, It has been a long time since I was last active here. In the early stages of homey I created some apps for z-wave devices. But along the way, I got other priorities. Now I am biting into a new thing. I have a Haier AC. There is no Haier app available yet. The wifi module is connected through USB and therefor easily replaced. The Haier ac’s consist of 2 types: - Based on hOn - Based on SmartAir There is a piece of software called “ESPhome” that can be installed on a Wemos D1 mini. And can than be controlled by Home Assistent. But i don’t have that, i have a Homey ofcourse 😃 Someone created a piece of ESPhome software which should connect the Haier hOn AC to Home assistent: [https://github.com/paveldn/haier-esphome](https://github.com/paveldn/haier-esphome) But I dont want to control my AC with Home assistent (for I don’t have that), I want to control my AC with my Homey. Fortunately, someone has started developping a Homey app for ESPhome devices. (which is than applied to the appstore by someone else without asking the developer!) [https://github.com/Inversion-NL/Homey-ESPhome](https://github.com/Inversion-NL/Homey-ESPhome) So now my plan is to add the ESPhome device for Haier AC into that app. [https://github.com/priknr1/Homey-ESPhome](https://github.com/priknr1/Homey-ESPhome) But, my programming skills for homey are quite rusty. I added a new device, and the app is compiling. I can fill in the IP and port for the ESPhome device, and it starts to communicate. But then I get the following error 7 times before a timout occurs: > 2023-04-14 18:11:38 [ManagerDrivers] [Driver:esphome-haier\_ac] Error on device 192.168.1.119: TypeError: Cannot read property ‘deserializeBinary’ of undefined > at deserialize (/node\_modules/esphome-native-api/lib/utils/messages.js:90:52) > at Socket.

What could cause this error? Does it maybe have to do with unknown capibily names? ---

Baldhor has picked up the development of my app. With my permission, this time. In contrary to the other app which was in the app store and is now replaced. > **[ESPhome](https://homey.app/en-us/app/nl.inversion.esphome/ESPhome/)** > > Control your ESP8266/ESP32 by simple configuration files.

Turns out the issue was in my Wemos board with the AC, not my connection from ESPhome to the wemos board. I was able to connect and control my Haier Airco from homey now. If anyone wants to do this, below is a summary of the steps. - Buy a Wemos D1 Mini (ESP PCB for a few euros) - Provide this with ESPhome firmware with settings for the Haier (for details see: [GitHub - paveldn/haier-esphome at experimental](https://github.com/paveldn/haier-esphome/tree/experimental)) - Make a connection for 5V, Gnd, Rx and Tx. (Details also in previous link) - Remove any original WiFi module from the Haier Air Conditioner and install the Wemos module - Install the ESPhome app on Homey - Add the air conditioning to “Hardware devices” via the ESPhome app - Add the air conditioning to “Virtual devices” via the ESPhome app - Link the desired functions of the Hardware Device to the Virtual device ---

Hello priknr1, I would like to get my haier ac in the homey app. Can you sell programmed wemos d1 mini devices with the right firmware already installed? best regards, ---

Problem with that is, it needs the WIFI SSID and Password in it, and I am not familiar enough with programming the wemos in a way that it would become Accesppoint where you could fill in the Credentials for your wifi yourself etc. ---

That indeed is a problem. Thanks for thinking with me! ---

When it can’t connect to your wifi, it should turn on AP mode. When you can’t find a wifi SSID to connect to, or when it just won’t connect: You can view and edit the yaml by connecting the board with a USB cable to a pc/laptop > [@\[HOW-TO\]\[Pro\] Using ESPhome devices - no additional hardware](https://community.homey.app/t/how-to-pro-using-esphome-devices-no-additional-hardware/90258/1): > > #### First install and run ESPhome itself on your laptop/pc: > > [Getting Started with ESPHome - ESPHome - Smart Home Made Simple](https://esphome.io/guides/getting_started_command_line) > > Here’s my local ESPhome page: > > > ![Screenshot from 2023-09-26 02-58-48](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/1/01b0036f4087110751045d36113832302fca2b81.png) ---
