Discover tasmota state result like mem & var

How can I access the stat/<my_tasmota_device>/RESULT topic published? I can see it in the HA MQTT integration “listen to topic” line and get e. g.

Nachricht 790 empfangen auf stat/SP13/RESULT um 11:55:
{
    "Mem1": "-30",
    "Mem2": "-12",
    "Mem3": "-18",
    "Mem4": "80",
    "Mem5": "12345",
    "Mem6": "",
    "Mem7": "",
    "Mem8": "",
    "Mem9": "",
    "Mem10": "",
    "Mem11": "",
    "Mem12": "",
    "Mem13": "",
    "Mem14": "",
    "Mem15": "",
    "Mem16": ""
}

but how can I access this in HA? It is not part of the autodiscover data form my tasmota devices. (The normal sensor readings and buttons or power states are all visible and used in my HA.)

Create MQTT sensor(s):

thanks. I added

  - platform: mqtt
    name: tasmota_status
    state_topic: "stat/SP13/RESULT"
    value_template: "{{ value_json.Mem1 }}"

Mem1 flickers in HA as the MQTT output comes in. It can’t be used. Leaving value_template away delivers a wild stream of changing json strings. How can I filter this correctly?

Here is what the tasmota device is spitting out continuously:

stat/SP13/RESULT {"Var1":"489","Var2":"day","Var3":"-30","Var4":"-32.000","Var5":"","Var6":"","Var7":"","Var8":"","Var9":"","Var10":"","Var11":"","Var12":"","Var13":"","Var14":"","Var15":"","Var16":""}
stat/SP13/RESULT {"Var1":"491"}
stat/SP13/RESULT {"Mem1":"-30","Mem2":"-12","Mem3":"-18","Mem4":"100","Mem5":"-2","Mem6":"","Mem7":"","Mem8":"","Mem9":"","Mem10":"","Mem11":"","Mem12":"","Mem13":"","Mem14":"","Mem15":"","Mem16":""}
stat/SP13/RESULT {"T1":0,"T2":0,"T3":0,"T4":0,"T5":0,"T6":0,"T7":0,"T8":0}
stat/SP13/RESULT {"Event":"Done"}

Best would be to have all of them visible in HA without much config.
