I have the IBS-M2-Kit. The M2 is connected to WiFi. I’m running the app on the latest iOS. I’ve connected my three TH2s. When I set it up it populated the TH2s as OUT2, OUT3, and OUT4. When I cycle with the CH/R Button on the M2, the M2 displays OUT0, skips OUT1, then shows the other three, then repeats. How can I reset the connections so I have OUT0, OUT1, and OUT2. Or at least OUT1, OUT2, and OUT3. It seems that OUT0 is actually the setting for display cycling. Where on my setup, leaving CH/R at, say, OUT3, leaves the display there and does not cycle. All this this is undocumented, although it’s hard to know for sure because I can’t text search the PDF file (Inkbird_IBS-M2-KIT.pdf). I unplugged the M2 and took the batteries out of the TH2s for seven hours but they kept their settings.
Hello,
Hello,
Please remove the sub-devices through the settings of IBS-M2 and then add the IBS-TH2s again. Will the channel change?
Thanks Tania, I didn’t know about that menu, and that’s what I needed. When I reconnected them I was able to choose the number for each device.
Hi Tania,
I have IBS-M2 GATEWAY with 3 of ITH-20-R-0 sensors, that are intermittent connected. Therefore get random notifications, on Inkbird App. I Select IBS-M2 Icon, enter into that Device to show ALL sensors with extra 6 of IBS-TH2 Plus sensors, therefore Total of max of 9 connected.
Get a notification that one of the ITH-20-R-0 sensors has lost Temporarily connection, sometimes BT Connection to this particular sensor is restored, therefore may only last <I hour. Completely random, then may work perfectly for days, weeks, months.
So also, I may lose a 2nd ITH-20-R-0 sensor, same issue, as before. But I also have an INKBIRD IBS-M2S GATEWAY with Same 3 sensors connected. Also working via another icon on Inkbird App.
So I can monitor, same sensors on both Options, as both are monitored, via Inkbird app.
I can then select either Gateway, and view same ITH-20-R-0 sensors, on the IBS-M2S Gateway ALL s Sensors are Stable, due to These Items being only within 1-2 meters, inside Garage monitoring T&H of Fridge and 2 Freezers.
At same time, these Same 3 of ITH-20-R-0 sensors, are being monitored on IBS-M2 GATEWAY inside House, some 20m apart, but for almost 12 months work perfectly. So no issues, but lately, over a month I get this intermittent connection issue.
Note: I have changed the Rechargeable Batteries, when battery level is less than desired level, ie “Empty”, so I Replace with Fully Charged Replacements. Battery Status is displayed, but always never Full, (Best at 3/4 Full) , which is as “Nominal Voltage” is less than Standard “Lithium” Voltage @ Full being 1.5v vs Rechargeable Battery “Nominal Voltage Peak” being 1.2v. Therefore Status never shows Completely Full, even though these Batteries are Fully charged.
So the reason for my post is that the Latest Inkbird App version 2.1.6.3 (Rel. Date 27/04/2026), does not have the Capability to Remove Sensors, as Displayed in the Screen Shot, shown above. (2024 version)
Below Recording interval setting - (Bottom edge of Display).
There are NO “REMOVE SUB-DEVICE” or “More Settings” exist now.
So needs to be RECTIFIED, ASAP
Cheers
Bob
