Shelly 1 Garage opener with DS1820

[rassual]

Hey, i use a few shelly 1 in my House and one in my Garage as door opener.

is it possible with the external plug-in an an DS1820 Sensor to show the Temperature in Homekit?

i can‘t find an solution here

Should be possible, but only by changing the code. Currently implementation excludes GDO see

This would be great also for Shelly Uni in gdo mode.

Please test this here if you want to (for shelly1, etc. not for shelly uni currently) https://github.com/mongoose-os-apps/shelly-homekit/actions/runs/7061601881

Excuse my ignorance, but how would one test this? I've got a DS1820, the add-on, and a Shelly Plus 1. Do I use the Python script?

If you scroll to the bottom of the linked page there is a build artifact called releases. This is a zip file containing all builds for all devices that you can download. You pick the Shelly plus one and upload it via webinterface.

ah sorry, obviously it cannot be accessed. I attached it here:

Thanks - thought I was going crazy as couldn't find any files on the page. I've downloaded it now and will give it a go over the next day or two. Cheers

Have now installed it and checked - can't seem to find any additional sensor information from the DS1820 as a GDO? Not showing on either the WebGUI side or the Home app side.

ah, I got the wrong build, can you try this: shelly-homekit-ShellyPlus1.zip

I've been using this firmware since you posted, and haven't seen any additional information from the temperature sensor in either Home or the Web page. The sensor doesn't appear when the Plus 1 is set to either switch or GDO. Anything to try?

[markirb]

Ok; not ok your side, there is the chance that a pin is wrong. I will get back to you. Your webinterface under version should say something like 2.10.1-152-gb6fab82-addon_unification correct?

Yep - see image

Okay good, can you try this one this uses gpio1, which should be correct according to tasmota… shelly-homekit-ShellyPlus1.zip

Just uploaded and no difference to the previous version, other than the temperature of the actual shelly is approximately 10º warmer than it was before... The webgui also takes a lot longer to load than the previous build.

Currently on build 20240210-193437/2.11.2-48-g68c79be

[markirb]

Ok strange… I will have a look again.If it’s hotter than better revert to an older version….But thanks for testing this

[markirb]

ok, i rechecked tasmota firmware. which has addon working since a few weeks. they seem to be using gpio0 and 1 for onewire out and in respectively... notably by arendst himself: https://github.com/arendst/Tasmota/discussions/20580#discussioncomment-8256030 I tried this here:

First impressions seem to suggest it's working..! Both Home and WebGui are successfully showing temperature values. Will keep you updated.

[markirb]

Very nice.

Now I'm interested why your garage has 41 degrees 😂😂

I'm not actually planning to use it as a GDO (or a switch really) but wanted to be able to get an external temperature sensor into HomeKit. Seemed one way of doing it with the bonus of a relay.

Doesn't work for my NTC sensor sadly, unless you know where to enable that?

[markirb]

What do you mean exactly? Is the scaling for DS18B20 incorrect? What exact type do you have?

I have the DS18B20 as a test sensor, I'll use it somewhere else eventually. It's within 1.5ºC of my Flir Infrared camera.

I'm using a 10K NTC Thermistor Sensor that wraps around a pipe in order to monitor central heating temperature, but it wouldn't show up. The wiring diagrams from Shelly aren't particularly useful at telling you which sensor is to be wired where.

[markirb]

Oh so you want to use the analog/ADC input of the addon? That is currently not supported… I have no idea how that one works, we only have the 3 digital inputs working just now.

Just an idea: Is there an ds18b20 or DHT with external thermistor that you can use?

[cameronaffleck]

There may well be... alternatively I'll cable tie the DS18B20 onto the pipe!

Thanks for all your help - seems to be still holding strong and no abnormal temperatures from the Shelly itself.
