Hi there!

Found this script and has been working great! I recently had to purchase a few TRVs from amazon and, even though it was the same seller, the devices I got had different manufacturer info (still same device 🤦‍♂ )

I changed this line: https://github.com/jmarsik/ad-eurotronic-trv-valvepos/blob/master/apps/eurotronic-trv-valvepos/eurotronic-trv-valvepos.py#L33
to this alternative:

if (v["attributes"]["product_name"] in self.args.get("look_for_productname", ["EUR_SPIRITZ Wall Radiator Thermostat"])):

so that on the app.yaml file I could just add:

  look_for_productname: 
    - "EUR_SPIRITZ Wall Radiator Thermostat"
    - "ZWA021 Thermostatic Valve"

I'd be happy to open a PR (over the weekend) but wanted to check up with you: as in theory it should be backwards compatible when look_for_productname could be both a string or an array, and both works with the in operator
