I should add that I have not connected to my AC yet, as I cannot find my pigtail wires, and it ain’t exactly a priority over keeping staff working (from home) and some money coming in!

so you do not know if you will actually get any data from AC? I have successfully compiled, connected, I can see it in home assistant, I just do not get any data from AC and it also do not responds to my commands.

For cabling I just found some od 2x8 pin similar connecto that was used to connect keyboard to some old electronics and cutted it down to keep only 4 pins.

Geoff Davis will probably answer on github.

Skipjack · March 28, 2020, 8:22am

Hi all,

I apologize in advance, I’m sure this will seem like very basic stuff but I’m struggling. Any advice would be appreciated. I have my Wemos D1 Minis connected to the AC units as per way back in this thread (built out as per the SwiCago/HeatPump README), and I can update them OTA.

I’m running Home Assistant 0.107.7 as a VDI within Virtualbox. I added the https://github.com/esphome/hassio repository to the add-on store, which gives me the ESPHome, ESPHome (beta) and ESPHome (dev) Add-ons, but all three show as release v1.14.3. I understand that this needs the 1.15.0-dev or greater, and presumably the 1.14.3 (dev) won’t do it. Are there steps someone I can follow to install the 1.15.0-dev version?
Because I’m running Home Assistant as a VDI image, and I can get to the command line via a Terminal / SSH add-on, by I suspect that I need console access to run the commands:

mkdir -p src
cd src
git clone https://github.com/geoffdavis/esphome-mitsubishiheatpump.git
I haven’t been able to get console access to work; at the “~ $” prompt I type ‘login’ and then get a “core-ssh login:” prompt. I give it the username ‘root’ and get a ‘Login incorrect’ return. Obviously I’m not doing the right thing here - any advice?
For the YAML configuration, in my configuration.yaml file I’ve included a line “esphome: !include esphome.yaml” and then created an esphome.yaml file in the same directory as my configuration.yaml file. In the esphome.yaml file I have put the ‘Example Configuration’ from Geoff Davis’ page (which I will then tailor). Will this approach work? (see below for what the file starts with…).

esphome:
name: denheatpump
platform: ESP8266
board: esp01_1m
# Boards tested: ESP-01S (ESP8266), Wemos D1 Mini (ESP8266); ESP32 Wifi-DevKit2
```
 libraries:
   - SwiCago/HeatPump
```
… and so on …

Any advice would be appreciated.

Skip.

Disregard on how to get console access. I found this thread on how to do a git clone with hass.io installed from an image.

I have 5 Mitsubishi units - all been working fine for more than month with
Couple days back I noticed that 1-2 of them got offline without any visible reason.
After some time offline they got back online without any intervention.

I did not use or re-flash them since March.
This morning 3 out of 5 are offline.
Units are working perfectly from remote control and permanently connected to power.
We did not have any power outage at all.

I trying to understand what happened.

Any ideas?

nickrout · April 10, 2020, 8:10pm

Look in the Logs?

mattl · May 15, 2020, 8:05am

I’m having the same issue. Were you able to resolve this?

nickrout · May 15, 2020, 8:07am

The answer was posted IN THE NEXT POST.

Pay attention

mattl · May 15, 2020, 10:49am

Yeah I tried using the dev version of https://github.com/geoffdavis/esphome-mitsubishiheatpump but has the same result. Could you please share your ESPHome config?

juanraesalua · May 20, 2020, 2:59pm

Hello did you get it to work?

nickrout · May 21, 2020, 5:54am

Sorry, this passed me by. My config that compiles, but I haven’t uploaded to the esp yet, is as follows:

I tried this on my Mitsubishi a couple of weeks ago and it didn’t work well at all… Everything was out of whack and the control/feedback did not work as expected at all… Put things back to the way they were. Will set up a seperate esp just to try this again when I have some time. I think I have some screenshots showing how it presented completely differently under Home Assistant too… I’ll post later.

juanraesalua · May 21, 2020, 4:35pm

I have my equipment right now running with https://github.com/gysmo38/mitsubishi2MQTT and it seems to work well

mihalski · May 21, 2020, 9:47pm

I was talking SPECIFICALLY about the esphome implementation.

AussieByrd · May 28, 2020, 11:52am

Has anyone been able to source pigtails (or even the 2mm JST plugs) locally in Australia? Revolectrix now looks to be charging $14+ shipping for the $1.99 item. And the only AU based seller I can find is charging $23 (for a $0.28).

mihalski · May 28, 2020, 1:53pm

Yes.
https://au.rs-online.com/web/p/pre-crimped-leads/5128737/
https://au.rs-online.com/web/p/pcb-connector-housings/4766798

But PLEASE quadruple check… It’s been a long time and I’ve ordered a bunch of stuff from them… I COULD be mistaken.

Should end up as $15.59. I did 3 units with that… But now I’m wondering how as I should need 12 pre-crimped wires…

AussieByrd · May 28, 2020, 2:07pm

Awesome… Thanks! I checked… seems right… comes to $14.83 (with the 150mm leads)

Skipjack · May 31, 2020, 6:10pm

I did - it works great. Was able to work through / learn about all of my issues above, and after flashing my Wemos D1 Mini Pro with something generic the first time round to make sure that OTA was working properly, I then used @nickrout 's yaml file shown above as my template, and everything works fine. Updates on my dashboard about 10 seconds after any input or temperature change.
