…for now I’m using this “ghetto-fix”:
I looked up the value for capacity via telnet and substituted “roombaState.capacity;”
root["battery_level"] = (roombaState.charge * 100)/2696;
I know the capacity will change over time but for now, I can get an estimate till the problem is fixed…
Perfect… I just ordered the board from OSH. Can you share detailed connection circuit?
Hi
How did you set things up? i have roomba 651 and Brodlink but dont know how to set it up?
Thanx
I just got @johnboiles code running on a nodemcuv2 with a buck converter and a 2N3906 PNP transistor:
vacuum/state {"battery_level":95,"cleaning":false,"docked":false,"charging":false,"voltage":14361,"current":-203,"charge":2581}
vacuum/state {"battery_level":95,"cleaning":false,"docked":false,"charging":false,"voltage":14361,"current":-203,"charge":2581}
vacuum/state {"battery_level":95,"cleaning":false,"docked":false,"charging":false,"voltage":14361,"current":-203,"charge":2580}
Sleep override is currently an issue because I am out of PINs fitting into the serial port. 
I had to make some adjustments for ArduinoJson 6 to get it compiling. PR is open: https://github.com/johnboiles/esp-roomba-mqtt/pull/37
Now I am going to try to get this thing into hass itself. What is the best way to achieve that?
It doesn’t seem this code supports MQTT discovery, right? https://www.home-assistant.io/docs/mqtt/discovery/
More news. My discovery implementation is running quite nice since some days on my Roomba 780.
You can find the code here: https://github.com/Armadill0/esp-roomba-mqtt/tree/mqtt-discovery_support
A second pull request to @johnboiles repository is open to get this upstream. Unfortunately there hasn’t been much activity on that repository during the last year.
I’m also experimenting with the locate support which I implemented by playing a predefined song. This is currently work in progress. Hopefully I can get this sorted in the next days/weeks. 
@johnboiles any chance u could update the diagram on git to show how to wire the wemos and wemos shield to work with your code?
I use https://github.com/mannkind/ESPHomeRoombaComponent on Wemos D1 mini. To which pin on D1 should I connect BRC that will work with this code?
You configure the pin in the ESPHome configuration. In the example roomba.yaml they use pin 4
I figured it out:
https://github.com/mannkind/ESPHomeRoombaComponent
BRC pin needs to be changed to 2 and then you have to connect Wemos D1 mini pin D4 directly with pin 5 on Roomba (no resistors).
And you have to use PNP transistor on RX pin as it is on
I am trying to compile this for my Roomba 650 using ESPHome (HASS.IO/Docker running on Synology). I am using the example ESPHome.yaml from https://github.com/mannkind/ESPHomeRoombaComponent, but receiving an error when trying to compile. I am pretty stuck with this, so would greatly appreciate any help.

@sergey732002 You need to pass in a compiler flag manually. I did this with the following modification to the yaml:
esphome:
name: rosie_roomba
platform: ESP8266
board: nodemcuv2
includes:
- ../ESPHomeRoombaComponent.h
libraries:
- Roomba=https://github.com/Apocrathia/Roomba
platformio_options:
[u] build_flags: -D HAVE_HWSERIAL0[/u]
Has anyone done this on an 800 series, specifically an 805?
I found a lot of guide for ones older than mine, but nothing for an 805
Working great on an 800 and 805 here. A small nodemcu or wemos d1 and a regulator even fit in the wheel well under the top cover.
Hi,
I have Roomba 860 and want to connect it to HA and I have two questions:
is this the correct shematic for connecting din connector to Wemos D1 mini (v2.2): Add wifi to an older roomba
I’m worried about connecting unregulated Roomba battery pin to 5V input on D1? What about those two diods in the picture?
@monaco @MarkDom
I don’t want to use MQTT, is there “regular” version with sensors exposed?
Thanks!
This guy has continued the Roomba ESPHome project, no MQTT https://github.com/Ceiku/ESPHomeRoombaComponent
Thanks, I managed to connect everything with homeassistant api, I wrote my own library.
@johnboiles is the git project abandoned? I would adopt it, maintain and also merge @Armadillo PR. It’s pity to leave this project to die.
Today I got a better idea how to connect our “dumb” roombas using builtin roomba addon. If we create a esp firmware which will simulate the behavior of wifi enabled roombas we won’t need MQTT or ESPhome running.
I’ve created an issue on roombapy repo, where I summarized what needs to be done. Read it if you like.
What do you think about this?
