Dear customer,
You can buy the Pixie timer from Amazon.uk and it will be directly shipped to you. https://www.amazon.co.uk/Netro-Faucet-Connected-Powered-Weather/dp/B085Z7K4BC?pd_rd_w=0Dfa4&pf_rd_p=6f3c660c-d5f2-4bb2-94a5-224dc9e931aa&pf_rd_r=2SZQ2VXCHGCAWPKM9G6F&pd_rd_r=fda88829-af30-4b0a-960d-8179e0c8962e&pd_rd_wg=s9hUY&pd_rd_i=B085Z7K4BC&psc=1&ref_=pd_bap_d_rp_1_i
Pixie works with the Whisperer sensor without needing a bridge, you will just need to make sure they are under the same wifi.
Thanks,
Netro Support
