Want to measure a battery voltage via Zigbee or Z-Wave device and have a tile in a dashboard showing D.C. voltage, current would be nice too but would settle for just the Voltage.
I have a 200Ah battery bank for my 20+ security cams, VOIP, network and cellular routers.
I use ZEN16 multi relays on that system.
I want to be able to monitor the battery voltage at battery, as post battery the voltage is stabilized to 13.8v using a buck/boost regulator so during a power failure the voltage is constant. I have a Low Voltage disconnect but it would be nice to have a fuel gauge so to speak....
Fibaro Smart Implant (ZWave) that has a 0-10V input, just make a voltage divider with a few resistors to bring the voltage your specs.
I have never used this device but I do use the Shelly UNI for this purpose (monitor engine and house batteries on my boat when at the dock) and it works great but the Shelly UNI is WiFi.
Errors when loading files from URL often result in loading a driver in the Apps area or an app code in the driver area. I’ve had this happen a lot - less now, but still does on occasion!
For Shelly Uni, it is a driver (not an app). Can you share a screenshot of the error you are getting if this was not the cause?
I'm using this driver (bundle) with a Shelly Uni. The Driver was easy to setup and works great. I'm using it to monitor the voltage of a vehicle with a parasitic draw that's only a problem occasionally. Works great.
It took me a bit to set up the Uni as the documentation is sparse but the community can help.
Ah yes, this one is different. If I recall correctly, @tomw’s link needs to be added to the Hubitat Package Manager (HPM).
If you aren’t familiar with HPM, it is a community app that was built to help people find and install apps and drivers. Here is a link to it:
So step 1 is to install HPM using the link (and instructions) above.
Then step 2 is to use the URL within the HPM app - there is a section to enter a custom repository.
In chrome on Android click on "view raw" and it will give you the option to download then you can import the zip file under bundles on the HE
I don't believe this is available on HPM and the driver in HPM I could not get to work with my UNI. This one was dead simple after the dev added the code for monitoring the voltage
I've been impressed with the Uni. The voltage matched my VOM which surprised me with a $12 device. I ended up using an old prescription bottle as my enclosure. A couple holes on each end for it to breathe.
