Hello everyone, I have an old <a href="https://carac.com.au/products/topargee-bluetooth-water-tank-gauge?variant=40540458320007&country=AU&currency=AUD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&utm_source=google&utm_medium=cpc&utm_campaign=PMAX_VIC&utm_id=20346123285&gad_source=1&gad_campaignid=20346124494&gclid=Cj0KCQjw_L_FBhDmARIsAItqgt77WOkC3LlVZwBnVG3olHevtU_llER1lC9BQtz9Zmic5eroIO0DKAAaAkV2EALw_wcB" rel="noopener nofollow ugc">e-flow inline Bluetooth water meter . However it is actually really annoying having a separate app to check water level. I can see that victron CERBRO has the ability to connect to Bluetooth sensors so it can show up on my touch screen. Has anyone connected an inline …

The Cerbo can not read random Bluetooth sensors, it has to be programmed to decrypt them. You may be lucky that someone has written add on script for this that answers, or can be found via a search or on github. Otherwise, consider the Mopeka level sensors which the Cerbo has been programmed to read…

So I have been learning Node-Red over the last few days and I think it may be able to help me! But I cant find out how to connect to random bluetooth devices. I know my device mac address but I don’t know which node to use to connect. I have tried a few community bluetooth nodes but sometimes the…

The eflow meter is branded as Topargee, but produced by Savant electronics as specifically for RV’s Part number BT-058L-44EF See https://www.digisavant.com/product/25 I have successfully connected the sensor as with 2 wires to the Cerbo Mk2 as a digital input, and after some trial and error, can r…

Hi @Snafud , Let me know if your still having trouble displaying as a tank. I figured that part out! Still struggling to get the ‘eflow’ to talk to the Cerbro Mk2 so I would love to know how you did that.

Hi Logan I can’t help you with decoding the Bluetooth. What i did was to buy a second sensor, install it and run the ground and signal wires to the other end of the ( canal) boat where the Cerbo is installed . NB you must have the Mark 2 Cerbo Then I just plugged into the digital input… I still…

What was the 2nd sensor you purchased? In terms of node-red I currently have a virtual tank showing up on my display which I can update by node red. The missing piece is a water sensor I can somehow connect to node red as well.

Hi Logan, The Topargee kit is I believe Savant Electronics kit rebranded as Topargee. Please check out www.digisavant.com . I think under products, you will find a Flow Meter that looks familiar, and also the sensor. Under their IoT section, they even have a hub to take the bluetooth to a cloud ser…

Thanks John! I will definitely look into that :smiley: As for your node red situation. I think I maybe able to help setting up a virtual tank. Hopefully this demo workflow below gives you the missing pieces on how virtual tanks work. [image] Since I don’t understand what you get from the ‘input…

Hi Logan, Thank you for the flow and coding - I was unaware of “Virtual Tanks” - I’m still on Chapter 1 of node red for dummies and that concept is possibly in Volume 2. Since I don’t understand what you get from the ‘input to pulse meter’ the following workflow will need to be tweaked to use that…
