Creation of a topic for 1-wire thermometers using an alias

[krzbor]

A very interesting feature of Heishamon is reading the temperature via 1-wire and sharing this value through MQTT. A special topic is created, for example: panasonic_heat_pump/1wire/2861755fb1220712. This topic can be used by various types of automation. However, the problem arises when replacing a faulty sensor with another one. In such a case, a new topic is generated, and the entire automation needs to be adjusted. Heishamon has a mechanism for assigning aliases to 1-wire sensors. Is it possible to add a new topic in the format: panasonic_heat_pump/1wire_alias/water_temperature, where "water_temperature" is the alias for the 1-wire sensor? This type of topic would only be available if the alias has been assigned, is unique, and complies with MQTT rules.

I am also vote for this feature, and also would like to extend with calibration possibility.

That i indeed the reason why I added the alias option. Currently it is added as a subtopic of the dallas-id in mqtt but that doesn't make it very usefull yet.
For backwards compatibility I'll keep adding the current method but I'll add the alias mqtt topic you described.

I'm very glad that the idea was well received. I wrote that the alias should comply with MQTT rules. I meant special characters. I'm wondering if it might be worth making one exception – for the "/" character. This would make it easy to create a subtopic.

I'm also using 1-wire sensor inside rules... so an alias would be great if ever needs to be "hardware" replaced.

on timer=2 then
$SensorBuffer = round(ds18b20#28ff641e8537c1eb);

Do you happen to know when this feature will be available?
