Feature Request: Home Assistant addon
Closed this issue · 21 comments
Hello,
could you provide this repo as a home assistant addon to be installed on the HA machine directly and be configured via the UI?
This will make an additional raspberry pi or machine where the docker image is running obsolete.
It would be a great advantage for HA users.
Thanks a lot.

Hello,
this is not generally possible because you need the connection to the hoval machine over the CAN bus on the machine that runs HA. I don‘t think that this is the case for most users (including me).
Greetings Christoph
I agree with @chrishrb.
It would be cool to port the code to something like ESPHOME. Then we would just need an ESP32 instead of a raspberry pi. Also the integration in Home Assistant would then be easy. I have this on my list, but did not start with it yet because the raspberry pi solution runs too stable :-D
haha same here. I wanted to rewrite the code in rust so I can run it on a microcontroller but i was too lazy (and there was not really a reason for it). Maybe in the next semester break 😄
I just started designing a PCB. 2x RJ45, CJMCU-230 (CAN Tranceiver), ESP32 Dev Kit v4, DC/DC Step Down Converter... Are any of you interested?

Yes I am. Do you plan to implement it with ESPHome? Thats currently my preferred solution if a HA addon will not be available and read already the esphome docs about canbus and ordered some boards to create some tests. Currently I have no Hoval HV but could be the choice in near future.

Me too, perhaps https://github.com/MagnusThome/RejsaCAN-ESP32 could help.
This is what I created, but I had no time to test the PCB yet. I have 4 spare PCBs if someone is interessted...
Can you share the easyeda project or source ?
(I mean the hoval can-bus power is 12V)
I'll post the full modbus-datapoints from hoval in PR
That version seems to works, at it's sold for 50€ https://raw.githubusercontent.com/wladwnt/CAN-Gateway/master/KiCAD/Version5/CANGateway.svg (but the software cost 130€).
I know this project but I do not like closed source projects. Also the PCB is too expensive for what I need.
The DC/DC converter has an input range of 7-24v.
I'll check how I can share the easyeda project.

Perhaps can you create a dedicated project on github ? I am not bad with esphome and electronics.
I propose to add an optional BLE0939 power sensor and an optional relay to turn off power
Why would you need relais and power sensor?

I have energy monitor in hassio and the relay is for fully stop the hvac. The minimum default runs at 15%

What is the DC/DC module you use ?
I like AMS1117-5.0

I do not know the chip on the module. "PEMENOL DC DC Step Down Modul"

But your is ?
The shield is done : https://github.com/nliaudat/esp_canbus
Next the firmware part ....
Wow that looks nice!
@chrishrb could you maybe also help here? We are confused about the can_id's to use.
I think we can close this issue because @nliaudat created a separate project for this use case. For questions please look at this repository.
