Sonoff D1 Dimmer

[MakoShark2]

Hi.

Looking to add a dimmer to control a ceramic heat lamp.

I've seen in the documentation that the Sonoff D1 dimmer is supported, but there's a note that it should be flashed with the Tasmota firmware.

Still this device supports a DIY mode which will open the API...

https://theroamingworkshop.cloud/b/en/1989/sonoff-d1-dimmer/

This is not supported at this time right?
I'll need to flash the firmware or support it through a dimmer script of my own?

Thanks.

At this moment, this dimmer is only supported when flashed with Tasmota.

I did not own this device, and somebody had this one with Tasmota. And you are the first asking for the Sonof own API.

So for now, it is easier for me to ask you to flash your Sonof dimmer with Tasmota, so it will work. When I have to make new code, it needs to be tested etc. That takes more time, and can make it more complicated. 1 device 2 ways of connecting.

Creating your own script dimmer relay can also work.

[MakoShark2]

OK. I think I'll be getting one (they are cheap) and try to create a script for the DIY mode.

If I manage to make it work I'll share the script, might be better to support it out of the box.

Thanks.

Made it work and was quite easy actually.

So the Sonoff D1 dimmer does work on DIY mode without the need to flash the Tasmota firmware (which is already supported by TerrariumPI).

In order to set it in DIY mode you'll need the RF remote as the dimmer do not have any button. Both are very affordable at the moment.

You can find the instructions here: https://sonoff.tech/diy-developer/

Also check TRW's detailed tutorial here: https://theroamingworkshop.cloud/b/en/1989/sonoff-d1-dimmer/

Once the dimmer is in DIY mode and connected to the wifi network the device will listen at it's assigned ip and port 8081. The ip should be known and configured as static in the network.

Then you can retrieve and command the device through the documented API: https://sonoff.tech/sonoff-diy-developer-documentation-d1-http-api/

I've used the provided script dimmer to build a script to interact with the dimmer.

I've attached the script file which has a lot of comments and should be very self-explanatory.

Product page: https://sonoff.tech/product/smart-lighting/d1/

I believe any Sonoff device which supports DIY mode could be easily operated the same way.

Ok, I have updated the code to try to support DIY mode directly based on your created script.

So the steps to test this are as follows:

1. Stop TerrariumPI
2. Update the code with git pull
3. Start in debug mode
4. Now try to add a new relay, with type Sonoff D1 dimmer with the address http://192.168.0.37:8081

Any errors should appear in the terminal if they are. You can keep the existing script version.

When the relay is added without errors, try to dim it. And see what happens.

I hope it will work. I could not test it... so try my best :D

[MakoShark2]

I'm running the docker container... Could this be done inside the docker container?

[theyosh]

Hmm, docker is a bit harder to debug and test.. I just made new development images. So you could run a test now.

The available development images: https://hub.docker.com/r/theyosh/terrariumpi/tags?name=development
Basically, just replace the version number with development should do the trick.

Then stop your docker container.
Change the docker-compose.yaml file
Do a docker compose pull to get the new image
Run docker compose up. This should start the container back up, but will leave the terminal connected to the container, so you can see the errors.

Than add a new Sonoff D1 dimmer like step 4 above.

I hope it works, as it is not possible to change the code in docker easily.

OK. I've switched to the development branch and added a the Sonoff D1 dimmer (Tasmota/DIY) at the specified address.

It's operated through the following Area:

It seemed to work well during the day time. When entering the night time the dimmer was shut to 0 as expected as the lower alarm temp is 4ºC lower and temp was well above that...

But then it showed a weird behavior. It seems to be constantly alternating between 0 and 98% (which was the last value of day time).

If I run the script to query the dimmer value it shows 0 all the time, so the dimmer seems to be switched off.

But TerrariumPI doesn't seem to agree with that and alternates between 0 and 98% which can be seen in the dimmer chart.

Please do not use the new relay in an area. Just add the relay and just try the dimmer manually. It will interfere with you script version every 30 seconds. But as long as there are no errors, it is good for me.

[MakoShark2]

OK. I've setup the area back to my script. Deleted the new relay, added it again this time without being assigned to any area.

It seems it's now failing on the reading:

I can ping the address and run my script from the command line which works fine and points to this address:port

Can I provide any other meaningful data?

[theyosh]

And thanks for finding this.

[MakoShark2]

I've pulled the docker container with the fix.

I've replaced the script with the new relay in my area, but I'm getting a weird behavior.
When it should be off (no alarms triggered), the relay (terrariumRelay) keeps setting 100%. The area (terrariumArea) seems to to work right by setting it to 0% just afterwards...
When the alarm triggered it seems work fine. The area will set the value according to it's target.

Will try to debug.

[theyosh]

Sorry for not looking in to that. Maybe we should start a new thread for that.

[theyosh]

What will happen when you empty the Power on time and Settle time values? Now you have the value 0. I think clearing those, should/could fix it.

[MakoShark2]

Not sure I understood. After clearing the power on time and settle time values, if I edit the area again those values are zeroed again.

I'll try to do some test during the weekend, with and without the area to see if I spot any particular behavior.

Oh, and we can start a new thread if you find it better.
