I tried everything and no matter what settings I choose it keeps changing from open to close on it’s own. I posted on the FIbaro forum, if we don’t get an answer there I’ll try to contact support.
Have you heard anything, really hope there is a solution. If it works then it becomes popular as a garage door control
Does anyone have any idea how long a 9 volt battery would last connected to the Smart Implant with one DS18B20?
Thanks in advance
@flth1968 I have submitted a ticket 3 days ago but they have not responded yet.
@makito The implant consumes about 20mA at 9V and a 9V battery has about 500 mAh so it would only last 20-30 hours. It was not meant to be battery powered since it’s always on and it also acts as a z-wave repeater.
@ovidiu.pruteanu thanks for the quick response. I have another idea which is probably crazy but thought I’d ask for opinions. I am planning to use my setup to monitor my hot tub temperature. I plan for my hot tub to only receive power for 8 hours a day. I am wondering if I used th 12v lighting circuit from my hot tub connected to a small 12v battery such as one from a UPS and then connected that to the Smart Implant if that would keep everything charged up and running. Thoughts?
@makito I actually need the same thing (a 12v UPS) for another device I’m working on, but I have not figured it out yet, I’ll let you know if I do.
I did a quick search and it looks like Fibaro had the battery powered FGK101 Contact Sensor which supported an external DS18B20, but it’s discontinued. Maybe they still have it in stock somewhere. Here is another topic about it.
@flth1968 Fibaro Support helped me track down the issue. I had to remove the “Refresh” capability from the Contact DTH. The implant does not support it and for some reason when the hub was sending that Z-Wave command to the implant it was changing it’s status to closed.
Does anybody know how often I should receive a temperature update from the DS18B20? Is there a way to increase how often this happens?
Thanks for your work, I tested the DHT without “Refresh” capability, without this parameter the status does not change but in the NEW app the device loses the connection.
I don’t know if it’s something to do with my wiring or whether it’s software. Here’s my setup (all using the same spec wiring). In a nutshell, my central heating is controlled via a zwave boiler switch, multiple DS18b20s, and 7 zwave radiator TRVs all connected via smartthings and webcore to set heating schedules. Essentially, if front room temp is supposed to be at 22 degs at 7pm, but the front room’s probe says it’s less than 22 degs, the trv opens, the boiler fires up, heats the front room and webcore rechecks the temps every few mins until the probe reads more than 22 degs (at which point the boiler/TRV is switched off).
(All fibaro’s mounted in ground floor ‘workshop’- initially powered by a single 12v 10amp DC PSU)
Fibaro UBS 1, 8m total wire running from workshop to rest of ground floor…i.e. low hallway, downstairs bathroom, utility and workshop (4 probes)
Fibaro Smart implant, 12m total wire running from workshop to 1st floor…i.e. mid hallway, frontroom, kitchen (3 probes)
Fibaro UBS, 16m total wire running from workshop to 2nd floor…i.e. top hallway, bedroom1, bedroom2, top bathroom, top hallway (4 probes)
I’ve been having odd disconnects , but only ever with the mid floor (i.e the smart implant). The top floor (the furthest away!) has been rock solid, no problems. Now from experience, odd intermittent issues tend to be down to power issues, so yesterday I used a separate 12v 2a PSU to power the implant on the mid floor.
oops. again, a disconnect in the early hours, only solved after a power cycle this morning just after 7am. During the disconnect, all probes on the mid floor registered zero degrees (see following image, just showing the frontroom ds18b20):
Now to be honest, I generally don’t get a lot of time although at the minute I’ve got more time on my hands because of lockdown. So on and off I’ve probably been on with this project for months and now it’s just starting to feel like a huge waste of time. The amount of time and energy that’s gone into this is fairly insane, and whenever I feel like I’ve got it cracked, I’ll check in to see that the central heating has gone tits up again because the probes have randomly dropped out.
I’m wondering if there’s any chance that this is down to software, as the other two floors seem just fine (both using UBS’s, not implant).
Any feedback most welcome ! = ) I’m close to just buying another UBS (sacking off the implant), but it’d be great if I could find out what’s going on, I hate unsolved problems! =P
@makito You can change the update interval with the parameter “68. External Sensors - periodical reports”
@Ivan78 You’re right, removing the refresh capability messed it up for the new app. I don’t use the new app very often and missed it, i’ll try to fix that soon.
@djh_wolf Not sure what to say about this issue. I have 3 implants that have been running for 5 months with no disconnects, but I do live in an apartment so signal strength will never be an issue. The only thing that I can recommend is checking the route of the implant’s z-wave connection in the IDE. Also, when it disconnects does the main device appear offline, or just the DS18B20 child devices?
Signal strength is spot on, it’s right beside the hub.
The probes still don’t work, I haven’t bothered power cycling.
Here’s a few images, let me know if you need anything else - I’m not sure what I’d need to send you, but I’m happy to help.
Here’s the implant in the IDE:

Here’s the implant in the app:

If you don’t mind, could you please tell me
(a) Which PSU you use for your implant (volts and amps)
(b) How many DS18b20’s are connected
© What sort of wire you use to connect them
(d) Are you using a pull-up resistor
(e) How long is the wire… from implant to sensor
Much appreciated, everything’s on hold at the minute as I just cannot get this working reliably. And obviously at the minute, none of the UBS’s work because this latest hub firmware seems to have really stuffed everyone. That bit is a little infuriating.
Much appreciated !
a) I have different PSUs for the 3 implants (12V 500mA, 15V unknown, 12V 2A). The one with the probes connected has the 12V 2A PSU
b) Two probes connected
c) Using the wire that came with the probe, like this one
d) Not using a pull-up resistor, but it is a packaged sensor and I’m not sure what’s inside
e) 2 meters
From your screenshots it doesn’t look like it’s a z-wave connectivity issue. The main device is ONLINE and is receiving updates from the internal temp sensor and the probe device is OFFLINE. So, it’s either a software issue, or the implant is loosing connection with the probes.
Scratch that. The device’s status is ONLINE, but it doesn’t look like it’s receiving updates from the internal sensor.
Thanks for the replies.
I’ll try connecting the probes at a shorter distance, powered by a single 12v/2a PSU, and see if that helps. It’s frustrating, because I need to literally wait up to a full day before I see if it continues to work. The amount of times I’ve reconfigured something and thought “aha! that’s fixed it!” only to find (as in this instance) the next morning, it’s knacked again.
Much appreciate your responses. Cheers!
I’m trying to implement a ZWave device to open my door lock from the intercomm button. With the smart implant can I program to close the circuit and trigger the door lock?
When someone is at the door and push the call button, a buzzer turn on (chime), can I use this device to trigger a switch in smartthings?
Thank you in advance.
I would like to use implant to allow me to open/close my electric gate. Currently the gate is controlled by a telephone interface (Videx ART 380).
Reviewing the interface manual (extracts below), would i be correct in thinking Implant ‘INI1’ should connect to ‘NO’& Implant ‘GRD’ to ‘C’, with the two wires i removed from the telephone interface connecting to Implant ‘OUT1’
Second question (not essential), could i connect Implant ‘INI2’ to ‘6’ to get a notification when the call button is pressed?
Any assistance would be appreciated.
Thanks in advance
I’ve just tried to remove the device in order to re-add with a single 12v/2a PSU and 4 probes connected very close by, no extensions in order to troubleshoot.
Here’s what’s now happening. I think this firmware release (for the hub) has broken even more things than first suspected, it’s really a piece of crap. Grr…
Manages to add the implant again as planned, but hub won’t let me delete the old one.
4 probes picked up no issues. I’ll leave it alone and see if it drops out again. The way it was (for me) ranged between a few hours and a few days before failing. So difficult to tell.
Also, appears my posts have been deleted in the main thread reporting these problems, presumably by the smartthings staff. It really does just keep getting worse.
Well, I don’t want to jinx anything, but right now, separate PSU (12v/2a as planned) and short cable runs… 4 sensors have been functioning for around 24hrs so far. I’ll continue to leave it and make sure it continues to work before jumping for joy and moving some wiring around.
Oddly enough though, the fibaro UBS (which is obviously currently unusable) has been relatively rock solid with the longest run to the top floor with 4 sensors. Which caused me to believe that the implant here should have been fine with the shorter runs. Odd.
