Dual temp sensors for TS0201 with dual endpoints

[papagenic]

This code implements dual temperature sensors on a single TS0201 device. The initial problem was to measure temperature on pipes, and very often temp measurements on pipes go by pair (input/output). Hence the idea to create a dual temp sensor from a single temp sensor

Only basic firmware versions are supported. I can't support all possible versions of homemade thermometers, as it would require over a hundred thermometers and components for testing. And that requires a lot of time. Organize a separate thread, agree on Zigbee firmware identifiers for OTA. I can provide a link to your version and take into account the firmware identifiers so that there is no confusion. Zigbee Board ID:

The BLE version supports assembly with 3 temperature sensors. Standard and 2 MY18B20 via 1-Wire. But this can only be assembled independently by setting 'define' in the configuration files. The same applies to other sensors. Water reserve tank management: ...

The next version of Zigbee will use the developments and similar codes of work with sensors from the BLE version. All source codes working with sensors will be changed.

Thanks for the input regarding sensors. I seem to remember however that the 1wire sensors are not so energy efficient. I guess you are probably right . The number combination of multiple sensors is very large. We can proceed as you suggest. What do you need from me for that? When you say "the next version of zigbee", do you mean the next version of ZigbeeTlc?

When you say "the next version of zigbee", do you mean the next version of ZigbeeTlc?

Yes, ZigbeeTLc. But there is no time yet. Also, a combination of BLE + Zigbee is suggested, since a very large number of users like to upload everything in a row, and then complain that there is no Zigbee or the existing system does not support Zigbee OTA. And BLE is on all smartphones...

Zigbee OTA files for existing thermometers are automatically downloaded to Home Assistant from https://github.com/Koenkk/zigbee-OTA. To identify which firmware is used for which device, the IDs transmitted by the device are used. Some have the update set to automatic.

Therefore, each version requires its own IDs. https://github.com/Koenkk/zigbee-OTA/tree/master/images/Telink

That's why it's not DS18B20, but Chinese MY18B20. And it has a significantly lower cost.

Works up to 1.8V power supply. And for additional reduction of consumption is used work in parallel with two 1-wire.

The entire purchased batch was also calibrated at the factory. The discrepancies in the tested batch of MY18B20 sensors are no more than 1 least significant bit. Comparison with SHT4x (lighter graph):

AHT10...35 sensors consume more and give a measurement error when powered below 2.5V.
