Dear all,
Ik like to control my Dru fireplace using Home Assistant. My Dru fireplace uses a Honeywell BRDG-03EM01 gateway. Using this gateway I am able to control the fireplace using the Dru app.
Some people got it working using OpenHab
The protocol is bases on modbus. Home Assistant supports modbus:
Does anyone managed the get the Dru fireplace control working in Home Assistant ?

I have this working with 2021.5
In configuration.yaml
modbus:

Nice @DennisF, thanks for sharing
For thos who are wondering, iāve setup some switches allowing me to turn the fireplace on and/or activate second burner, (eco) wave:
- platform: template
switches:
fireplace_status_wave:
friendly_name: "Fireplace wave"
value_template: "{{ states('sensor.fireplace_status_raw')|int|bitwise_and(512) > 0 }}"
turn_on:
service: modbus.write_register
data:
address: 40200
unit: 2
value: 105
hub: fireplace
turn_off:
service: modbus.write_register
data:
address: 40200
unit: 2
value: 7
hub: fireplace
fireplace_status_main_burner:
friendly_name: "Fireplace Main burner"
value_template: "{{ states('sensor.fireplace_status_raw')|int|bitwise_and(4) > 0 }}"
turn_on:
service: modbus.write_register
data:
address: 40200
unit: 2
value: 101
hub: fireplace
turn_off:
service: modbus.write_register
data:
address: 40200
unit: 2
value: 3
hub: fireplace
fireplace_status_second_burner:
friendly_name: "Fireplace second burner"
value_template: "{{ states('sensor.fireplace_status_raw')|int|bitwise_and(8) > 0 }}"
turn_on:
service: modbus.write_register
data:

value: 102
hub: fireplace
turn_off:
service: modbus.write_register
data:
address: 40200
unit: 2
value: 4
hub: fireplace
Note 1; the Hub value is the name you define in your modbus configuration
Note 2; Either the second burner of main burner turns on the fireplace
also some other states I read via:
- platform: template
sensors:
fireplace_status_fault:
friendly_name: "Fireplace fault"
value_template: "{{ states('sensor.fireplace_haard_status_raw')|int|bitwise_and(1) > 0 }}"
fireplace_status_pillot_flame:

Ah totally forgot to post how to do things, here are my different scripts which steer the fireplace

Great i was looking for this long time. are the scripts also placed under configuration.yaml?
That depends a bit on how youāve laid things out but without any fancy layout, yes.
Integration of your first code is working. however the last 2 scripts are giving me an error.
homeassistant.exceptions.HomeAssistantError: The system cannot restart because the configuration is not valid: Component error: huiskamer_haard_uit - Integration 'huiskamer_haard_uit' not found.
Component error: sensors - Integration 'sensors' not found.

@Dennis : thanks for helping me out 
@Stingtone : regarding the error. Put the following lines in your configuration.yaml
# Includes
script: !include scripts.yaml
And put DennisF code in the scripts.yaml

Hi,
I canāt get this to work. either I have a modbus error
ā2022-01-08 14:18:13 ERROR (MainThread) [homeassistant.setup] Setup failed for modbus: Invalid configā
or the sensors are available but do not give any data/update.
Can you share the input to put in the configuration.yaml and scripts.yaml?
Iām doing something wrong, but really cannot figure out what it is that iām doing wrongā¦ 
Thanks!

For people looking for dru fireplace integration (with the Honeywell bridge) I have created a āsimpleā setup to add this to your own HA.
Still work in progress and I am hoping to get it perfect soon.
Tips are welcome.
Hello Firewizz,
just installed your integration. Works great, I am very happy with it.
Thank you very much,
Simon
Hello,
I also installed this inegration and it seems to work fine.
However, when I do so, the apps on my phone/tablet stop working with error message: āGateway errorā.
Any idea why?
Thanks,
Harmen
Sorry for the late reply,
Who is giving the error, the home assistant app? Or is it in the logs? Is this only on mobile devices or also when logged in to home assistant using browser?
Hi Nemrah and Firewiz
Did you get this fixed? I really appriciate the integration, Firewizz - but I have the same problem. The app stops working.
My apologies for the late response.
I havenāt made any changes yet. Didnāt get a response to my questions.
At the moment I am super busy but maybe next week I can check if I can find a solution.
Super and thank you. What Iām experiencing is that the DRU app on the phone comes with the error āGateway errorā. Not sure how to investigate more. But let me know if there is anything I can provide to help.
Hi, do you mean the original app stop working? Not the HA app?
You can solve this by increasing the timeout. As a default since I do not use the original app and only the HA app I put this on the max. So it could be that the gateway stops accepting connections/updates.
Iāve got a couple of settings you can play with (in /packages/dru_fireplace.yaml) :
Please let me know if one of these helped!
Hello
I have now tried timeout from 1 to 50 and delay from 1 to 20, but same result. The Dru app does not work.
Iām considering using Home Assistant instead. Can you also control the level (the size of the fire from 1-15) in any way?
