I have in installed the battery. I have look at a Shelly Uni but the max voltage is v10 and I have 12v battery's.
The Uni has 2 settings. One for up to 12v and another for up to 30v. Mine are set to up to 30v.
Did you purchase your Shelly Uni device yet?
I jest bot one. ware did you git the driver?
Gosh I wish there was a Zigbee version of something that could address this exact use case.
You’ll need to install the Community app called Hubitat Package Manager (HPM) if you haven’t already done so.
Here is a link to the community page that explains how to install it:
Once you have HPM installed, and from within HPM, you can install the Shelly Uni driver using the "From a URL" option in HPM, here: https://raw.githubusercontent.com/tomwpublic/shelly_experimental/main/packageManifest.json
I jest got mine in. Now how do I wire it up to my 12v battery's? I jest got my Shelly Uni in today and jest tried to setup in hubitat. I testing by using by on/off but it is not working.
Here’s a picture showing how mine is connected: Red and white together on +; Green and Black together on -.
Once powered up, you can access its web interface by connecting your phone or tablet to its wifi. Based on the above, I assume you’ve completed the steps above - is that correct?
Can you show a screenshot of your Hubitat configuration?
Is there another one of these shelly unit that is basically plug and play I accidentally burnt the one I have up by hooking it up backwards negative to positive. I would rather have a unit that comes with plastic on it and all you do is plug positive in the positive and negative and negative and it's labeled All I got to use two wires not a barrel jack.
You need to go to the « Shelly Uni-adc0 (Shelly Uni-acd0) » device in order to see the voltage:
I am not aware of any other types of UNI devices than those. My son printed cases for mine, but the same cables come out…
I have 48v system which could top out at 58V, anyone put a voltage divider in to drop the ADC input down below the Shelly's 30V max input?
okay what Shelly Uni that does not use a barrel jack?
The device you see on the bottom of my picture is actually a barrel plug. The device otherwise doesn’t come with one.
I have a Renogy charge controller that connects to my phone via Bluetooth I am looking at but I'm not familiar with home assistant people say they've gotten it to work with home assistant using a raspberry pi. They provide the necessary files but I don't know how to put them in home assistant and then tie home assistant into hubitat? Any help would be appreciated at this point? I have home assistant up and running on a raspberry pi at the moment.
