I think the reason you’re not seeing that kind of device is that zigbee is designed more for low-bandwidth, sporadic updates rather than continuous streams of live data like you typically expect from a probe thermometer.

Not OP, but I've been looking for something like this. I've got a couple of refrigerators and a deep freeze I'd like to monitor. I'm not looking for a cooking tool that constantly sends updates. For that I'd like to use a multi-probe Bluetooth device. I've got Zigbee for other sensors, and I'd like to add these to the net
Yes, same. I'm just looking for an update every 5/10 minutes, so I can chart the temperature throughout the day.

Sounds like little project for an ESP32 with a few DS18B20. With ESPHOME they are really easy to set up.
For my own morbid curiosity, why Zigbee?
If you don't want to learn ESP Home yet, but you're ok with Wifi, here's a sensor that uses ESPHome, but is all pre-programmed and ready to go with Home Assistant. I haven't used this produce yet, but the other products from Apollo are pretty awesome.

Are you looking for a long probe, or a small probe on a long cable?
Sorry, yes, small probe on a longish cable. It's for measuring temperatures on various pipes and hot water tanks to try and understand our new wood stove central heating a bit better.
Hey, this is exactly what I wish to accomplish.
I haven't found any readymade device either..
I have bought all the parts needed, but like you, I don't have the patience/time to put them together.
The reviews aren't the best, but I did find this recently. Haven't tried it out yet.
That's the one I got, but home assistant only sees the switch, not the temperature.
There's a thread about adding the temperature that you could try.
I would do this with a home-made esphome (like other have suggested). If it has to be a commercial product, you can buy the shelly addon and attach it to any of their Z-wave 1pm products like this one for example.
The addon supports up to four temperature probes and the cables can be many metres long.
Check out this device. I have several and they work well. Zigbee temperature sensor in a cabled probe.
That looks great!
