Filter negative values in MQTT Publish automation

Hi

I’m fairly new to HASS.
I’m running the Huawei Solar integration and it’s working almost perfect.
I’ve created an automation to send my current power (coming from my solar panels) and total daily yield via MQTT to Domoticz using this code:

service: mqtt.publish
data:
  topic: domoticz/in
  payload: >-
    { "command": "udevice", "idx": 728, "nvalue": 0, "svalue": "{{
    states.sensor.active_power.state }};{{ (states.sensor.daily_yield.state) |
    round(3) * 1000 }}"}

However… everyday at 6AM, the daily yield value gets reset to 0. This results in a big negative value being send to MQTT/Domoticz. Is it possible to filter out a negative value in states.sensor.daily_yield.state please?

Tnx!
