Interesting, what about piezo beeping while arming and when the alarm is triggered (with entry delay) @premiumtouring?

If that's the case maybe I will just get the normal konnected boards 👍

@gcorgnet sorry for semi hijacking your thread. Provided your Bosch alarm panel has 12vDC AUX outputs then its fine to use that but make sure its DC not AC. During my research I found others doing that to utilise the battery backup of the alarm panel.

User either openHAB or HA purely for 'dashboards', but everything else clever, do it with Node-RED. You then actually spend time working on automation's rather than chasing stupid bugs.

A separate topic really....but I found node read a real punish (more so that HA) compared to the flexibility from openhab rules. Dealing with multiple conditions was a pain in both. Maybe that's because I have a coding back ground I don't know. But attempting to get my heating scheduling from openhab to HA....and since I couldn't do it with an automation I tried node-red...but that became a big spaghetti junction of lines.

Yep, piezo buzzer and all. I essentially recreated the Bosch alarm experience and then completely modernised the alarm experience by stream lining the basic stuff and adding tonnes of additional value and communication afterwards.

Won’t be long til the guide is finished.

Regarding powering the Konnected board. According to this, it is possible to power it up ising the Aux output of the exiting Alarm Panel.

Has anyone done that with a Bosch system? Would that take advantage of the backup battery and avoid me having to worry about backup power?

Technically possible to power Konnected by rerouting the 12V leads going to the bosch panel, but no battery backup as the battery charging and switch over circuitry are on the bosch panel.

I would have thought that regardless of the fact that you unhooked the sensors and siren from the original panel, that panel would still be powered and therefore would still be able to provide 12V, including battery switchover when power is lost... or am I missing something?

The Bosch panel doesn’t provide 12v power out, it accepts 12v from the exposed mains transformer inside the panel. It then passes that power on to a 12v battery which switches from charging to drawing when there is a loss of power.

Right, thanks for that. So you're saying I can reuse that 12V coming from the transformer (thereby completely removing power to my Bosch system) but the battery will not take over... I see. Maybe that Sentry could help there...

It definitely could hence my intrigue when you mentioned it.

although you would ideally wire it in... I guess you could plug the output of that 12V transformer into the sentry? (maybe some DIY wiring there) and then power the Konnected from the Sentry

If you're game enough you could get this https://konnected.io/collections/in-stock-now/products/backup-battery shipped to https://www.myus.com/ who will send things like that with properly marked packages using DHL.

I had them ship this, it did take awhile to arrive though

I'm little confused by this... The output of the transformer is AC and will be around 18v- so not suitable to power the konnected board

I believe the Bosch board will be able to power the Konnected board - it would just have to be wired to the GND and +12v terminals on the board. So effectively you could just disconnect everything from the Bosch board apart from the power input and battery - then power the Konnected board from the GND and +12v terminals. Keep in mind you would lose some of the battery capacity to the Bosch board being powered. This would therefore allow you to use battery backup from the existing Bosch board. You would still need a way of maintaining power to the router, etc in a power cut.

Yep, theoretically true but inefficient, likely to cause issues and plainly not recommended. Best solution is to get rid of the exposed 240v AC, so that you can wire it up like so..

Just to post an update, I have been looking at my existing system and how it has been wired, etc..

It does look like I have one free Zone and 2 free output which I could re-program to work with the Konnected Interface. At this stage, this would still be my preferred way of doing it as it does leave me with an system that does not depend on HA or my newtowk to be up to function.

I am now busy trying to hunt down my "Installer Code" to re-program the outputs. Any suggestion here would be appreciated.

Managed to ring the guy who did the electricity in my house 7y ago (lucky he didn't change number) and he gave me the installer code (lucky he remembered it)

I can now re-program the unused Zoness/output of my alarm which means I will be attempting to fit a Konnected Interface onto my existing system so as to keep it intact and functionning, albeit with smart functionality.
