There is a possibility to integrate these sensors into Home Assistant. Here is a short tutorial, it is no longer up to date, but if you are a bit experienced you can do it: https://www.107er.net/hitech/2019/02/mobilealerts-sensoren-in-home-assistant-einbinden/ In general, the data is redirected via an MQTT proxy and intercepted there. Bad luck for TFA, who no longer get the data, but it's their own fault if they don't keep up with the times here. The products are great.
