Is there a way to connect Inkbird IBS-M2?

Add-ons Bindings

Hi,

I’m looking for a way to get water temperature from this sensor. Is it possible somehow? Have anyone been able to achieve it with this device?

Best regards,
Pedro

Hi @pedrolima

I assume it is the actual IBS-P02R pool thermometer, in conjunction with its IBS-M2 gateway. Is that correct?

If so, the IBS-P02R itself should be receivable with the rtl_433_ESP version OpenMQTTGateway on a LilyGo LoRa32 v2.1, or any ESP32 with a CC1101 connected (the LilyGo will have a better reception range)

Alternatively any other rtl_433 implementation should be able to received it.

Both above solutions can easily be integrated into openHAB through the MQTT binding.

There might also be a direct binding solution for the IBS-P02R I might not be aware of.

EDIT My bad, I seemed to gotten confused with the 20R instead of the 02R :frowning: but since the IBS-P02R also seem to work with 433MHz RF transmission it should be integratable into rtl_433 - or maybe not, or through the WiFi of the gateway station.

@pedrolima FYI - the Bluetooth versions of the pool thermometer IBS-P01B or IBS-P02B can easily be connected to openHAB.

That is very interesting indeed. I will look into BLE2mqtt devices and might use that for this one. I’ve also ordered this device which I think it’s much more interesting, not only because of the price, but because it is connected via USB (so no worries about batteries), it is not directly in the sun (so no fast deterioration as many complain) and the cheap water sensor, I’m ok if it is not much precise because I only want to have an idea of the water temperature and then turn ON or OFF the heat pump with a Shelly. As simple as that.

Anyway, in my case this will be more of a “gadget” and one more thing to see in my APP rather than a useful functionality because I have solar panels and batteries and I’m 100% self-sufficient, with excess being lost anyways so I will probably just keep the heat pump running always and that’s it…

Still, thank you for your inputs. :slight_smile:

I’m using several Inkbird BLE thermometers via ESPhome – the ESP32 device captures the BLE broadcasts and they show up in OpenHab via the ESPhome binding with channels for temperature, humidty, and battery level.

The same ESP32 captures broadcasts from my RadonEye radon monitor.

Edit to add that I have the IBS-P01B pool thermometer, but haven’t used it yet as the hot tub is still winterized.

Thank you for your feedback. I am now trying this device which connects perfectly fine with Tuya and was easily discovered in OH.

Problem is, the Thing added now reports:

HANDLER_INITIALIZING_ERROR
A unit hint must not be set if the item type is not a number with dimension!

I’ve even tried to add it manually, by adding a Generic Tuya device and inserting all necessary data, but unfortunately it gives me the exact message.

Any suggestion on how I can “override” this somehow?
