Broadlink RM4 Mini or Sensibo?

You should be right to use the Generic Thermostat integration for that.

I have a technician coming out Friday to take a look - he recommended the Airtouch even though he’s a Daikin retailer, said that the individual room controls are a lot better than Airbase as Airbase can only have ~ 2 degrees variation in the system. He’s also a home assistant user so at least he understands what I’m trying to achieve.

@tom_l i recall reading about your solar and aircon automation - what size solar installation do you have to achieve that much excess power?

Through office works or somewhere else?

Mahko_Mahko · December 1, 2021, 10:33am

Just off the Office Works website… Same as up here…

jivesinger · December 1, 2021, 10:51am

For those with the Daikin Airbase interface - is this a cloud based device or is there local access available ?

Also, prices online are around $250 to $300.
Is this around what you paid / expected price ?

Thanks.

tom_l · December 1, 2021, 11:01am

Totally local.

Just looked at my quote for the BRP15B61, $350

DHT22 connected to an ESP.

8kW of panels with a 6kW inverter.

I have that same setup too David. SolarEdge 8.25kW 3-phase connected via the HA SolarEdge modbus integration and ethernet.
Way better than their cloud access, which dropped out for me for hours at a time.

Shifted question to the recently discovered Genio product thread…

mr.sneezy · December 5, 2021, 2:16am

Damien, I’m using Daikin Airbase on a 3-phase ducted system with 6 outlets.
I have some automations controlling it, to start the system only when there is enough solar power from my inverter to cover the load (usually by 8:30AM in the morning) and the inside temperature is rising above 22C.
Works well for me. Zone opening or closing is also controlled by HA via Airbase
I did have some fun working out which functions applied to my AC unit and the OEM Daikin zone controller, but once sorted it’s been great.

teleksterling · December 6, 2021, 12:58am

Thought I’d share my setup here too - I’d love to hear from anyone else who can add more.

I have three Daikin Cora split systems, different capacities, each with the daikin wifi modules attached.

FTXV95LVMA 9.5kW Cora split system
BRP072C42
Power/mode/temp only (not fan speed, tilt/pan, etc)

FTXV71UVMA 7.1kW Cora split system
BRP072C42 + BRP980B42 auxillary PCB
Power/mode/temp/fan/silent/pan/tilt

FTXV46UVMA 4.6kW Cora split system
BRP072C42 + BRP067A42 auxillary PCB
Power/mode/temp/fan/silent/pan/tilt

The limitation on the controllable functions for the higher power (>7.1kW) units is common to the HA integration and the Daikin app. I followed up with Daikin tech support, and the short version is that it’s a limitation of the different hardware on those units (I don’t know the details). I asked whether it’s something that may be addressed by a firmware update of the wifi module or the AC units themselves (OTA or otherwise) and they said that no, they don’t do firmware updates for the wifi modules - i.e. if it was to be changed it would be a new model, with new model number.

My takeaway from it was that the only way to be able to control the fan speed/pan/tilt using anything other than the provided IR remote is to purchase and use an IR blaster device. So I followed up by asking whether they publish (or would provide) the IR codes, to which she also said no.
I to ask her whether the IR remote sends the full desired state (all settings) on each button press, or just the changed setting, but we struggled to communicate. The answer she gave was that it only sends the change the user inputs. But I’m not confident on that, Especially because afterwards I found sites like this which detail a user’s reverse engineering of the messages which contains all of the state options together!

From a HA point of view, I guess using this would involve some sort of template climate entity where (all or some of) the instructions are sent via IR, and the status is pulled directly from the wifi adaptor.

mr.sneezy · December 6, 2021, 8:56am

If you are technically inclined one of these is gold for reverse engineering IR or RF serial data devices.
I’ve unlocked quite a few devices with one. The PC software can decode a LOT of common protocols.
You can connect to the LED on the TX, or use an IR diode to detect the serial pulse frames.

sparkydave · December 6, 2021, 9:53am

Tempted to get one and see if I can work out how to interface to my evaporative A/C via the wall controller.

tom_l · December 6, 2021, 10:01am

I’m not sure if that is some sort of knock off or what. The Saleae website has much more expensive versions https://www.saleae.com/

sparkydave · December 6, 2021, 10:26am

Much more expensive would be a gigantic understatement

One thing the eBay one doesn’t say it includes is software. @mr.sneezy is that the exact unit you have? Did you get software with it for free?

tom_l · December 6, 2021, 10:28am

Yeah, I was looking for the software when I found that site. Also interested in the answer.

mr.sneezy · December 6, 2021, 12:32pm

Yes, my unit is as far as I can tell exactly the same unit, sticker, LED’s and all. Mine runs with Saleae own software. I’m using Logic 2.3.39 with it.
These have been around a long time, I think mine is about 5-6 years old, perhaps this version was an open design at some point.

Also here on Amazon AU
https://www.amazon.com.au/Comidox-Analyzer-Device-Channel-Arduino/dp/B07KW445DJ
Down the bottom it suggests it’s also compatible with software called PulseView, but I’ve only ever used Saleae software with mine. Saleae software is free also.

Also found here on a great AU site I buy from for work.
https://core-electronics.com.au/usb-logic-analyzer-25mhz-8-channel-43841.html?

Mine was off Ebay, and was about $10AU at the time…

I see the alternative software supports at least 5 common IR protocol decoders.

sparkydave · December 6, 2021, 11:27pm

I do like core-electronics but most of their prices are far above what can be bought elsewhere, even within Aus.

Thanks for the info.

sparkydave · December 6, 2021, 11:59pm

Just got emailed with info on a new device, made in Aus too!

mr.sneezy · December 7, 2021, 8:59am

I think this is a good deal on the logic analyzer, and they have good buyer feedback.

From doing some checking it seems the open source software is the way to go when using these units, which apparently were all originally based on the main chip datasheet suggested schematic anyway…

I’ll try it myself too.

Hi,

I have 8 of these brilliant ceiling fan controllers and I am having some issues getting the new HA config to work. I used this Brilliant Smart Ceiling Fan Remote in Home Assistant blog post to set them all up and they all work fine. The big diff from this blog post (Taking the old ceiling fan for a smart spin – neon.ninja) is that it stores the RF data in the HA config file, not in the device (fan) config.

Below is the YAML that was working, is there just a simple way to convert this?

fan:
  - platform: mqtt
    name: "esp_fan_bedroom"
    unique_id: "esp_fan_bedroom"
    command_topic: "cmnd/esp_fan_bedroom/POWER1"
    state_topic: "tele/esp_fan_bedroom/STATE"
    state_value_template: "{{ value_json.POWER1 }}"
    speed_command_topic: "cmnd/esp_fan_bedroom/Backlog"
    speed_state_topic: "tele/esp_fan_bedroom/RESULT"
    speed_value_template: >
      {% if value_json.TuyaReceived.Data == "55AA03070005030400010016" %}
        Power1 1; TuyaSend4 3,0
      {% elif value_json.TuyaReceived.Data == "55AA03070005030400010117" %}
        Power1 1; TuyaSend4 3,1
      {% elif value_json.TuyaReceived.Data == "55AA03070005030400010218" %}
        Power1 1; TuyaSend4 3,2
      {% endif %}
    availability_topic: tele/esp_fan_bedroom/LWT
    payload_available: Online
    payload_not_available: Offline
    payload_low_speed: "Power1 1; TuyaSend4 3,0"
    payload_medium_speed: "Power1 1; TuyaSend4 3,1"
    payload_high_speed: "Power1 1; TuyaSend4 3,2"
    payload_off: "OFF"
    payload_on: "ON"
    qos: 1
    retain: false
    speeds:
      - "off"
      - low
      - medium
      - high

I have tried adapting the other configs (which require setting the RF data in the device config) and it just doesn’t work

  - platform: mqtt
    name: "esp_fan_bedroom"
    command_topic: "cmnd/esp_fan_bedroom/POWER1"
    state_topic: "stat/esp_fan_bedroom/POWER1"
    payload_on: "ON"
    payload_off: "OFF"
    availability_topic: "tele/esp_fan_bedroom/LWT"
    payload_available: "Online"
    payload_not_available: "Offline"
    preset_mode_state_topic: "stat/esp_fan_bedroom/RESULT"
    preset_mode_value_template: >
      {%- if value == '3,0' %}Low
      {%- elif value == '3,1' %}Medium
      {%- elif value == '3,2' %}High
      {%- endif -%}
    preset_mode_command_topic: "cmnd/esp_fan_bedroom/TuyaSend4"
    preset_mode_command_template: >
      {%- if value == "Low" %}3,0
      {%- elif value == "Medium" %}3,1
      {%- elif value == "High" %}3,2
      {%- endif -%}
    qos: 0
    preset_modes:
      - "Low"
      - "Medium"
      - "High"

Rules:

Rule1 
on TuyaReceived#Data=55AA03070005030400010016 DO Publish stat/esp_fan_bedroom/RESULT {"Speed":1} endon 
on TuyaReceived#Data=55AA03070005030400010117 DO Publish stat/esp_fan_bedroom/RESULT {"Speed":2} endon 
on TuyaReceived#Data=55AA03070005030400010218 DO Publish stat/esp_fan_bedroom/RESULT {"Speed":3} endon
Rule1 ON


Rule2 
on Event#speed=1 DO Backlog Power1 1; TuyaSend4 3,0 endon 
on Event#speed=2 DO Backlog Power1 1; TuyaSend4 3,1 endon 
on Event#speed=3 DO Backlog Power1 1; TuyaSend4 3,2 endon
Rule2 ON

Appreciate any help, as getting hot here as we get into summer, and my family loves them working in Apple Home.
