Missing old P1P2/P/XXX/C/1/ topics

[corruptux]

This weekend, I updated the firmware to the latest recommended versions (bridge v0.9.57 and P1P2Monitor-v0.9.58Daikin-E). Previously, I was using versions v0.9.43 and v0.9.42.

I’ve noticed that the structure of the MQTT topics has changed. It’s nothing serious that I can’t adapt to, but now there are significantly fewer elements. I’m not sure if this is due to an autodiscovery error or if it’s intentional by the developer.

Some of the old topics were very useful to me, specifically all those under P1P2/P/XXX/C/1/.

In particular, P1P2/P/XXX/C/1/Starts_Compressor was essential for monitoring the machine’s start-ups and shutdowns, helping me avoid having to replace the compressor again (as it failed in less than 4 years).

I don’t use Home Assistant; I use Jeedom. Is there a way to reactivate the missing topics, either all of them or just some?

Thank you for your help. Best regards,

It should still be there, with a prefix which no longer depends on the IPv4 address of the bridge ("XXX" in your example) but which depends on configuration parameters P24 and P28 (default both 1) and the device/bridge name (default P1P2MQTT / bridge0), as P1P2/P/P1P2MQTT/bridge0/C/1/Starts_Compressor, but these counters are only available if you enable Counter_Request_Function (command C2).

Without Counter_Request_Function, counters are intentionally no made available any more, as the counters were then taken from the main controller instead of from the main unit, resulting in outdated counter information.

Out of curiosity: how many compressor starts did your system have when it failed?

Thank you so much for your help. I'm sending you a coffee.

The machine was installed in March 2017 and broke down in March 2023. It had 19,112 starts during that time. Now it's at 2,165.
I bought the module from you and started with home automation to take care of the compressor. I've gone from almost 70 starts per week to less than 20.

Thank you very much, and you are welcome of course! 19k starts is a lot for 4 years but does not seem that high to me for full failure, so perhaps you had bad luck too - I was led to believe compressors should last 50k-100k starts. Mine has 27k starts after 10 years. 20/week or 1k/year is really good.
