I got a bit annoyed when Heatmiser EOL’d their range of WiFi heating thermostats, and replaced them with SmartStat and NEO range. For a start the SmartStat can’t be talked to, and the NEO needs an extra hub box, making a purchase of a single thermostat about ?175.
So I found a new Thermostat range from a company called BecaEnergy (http://www.becaenergy.com), and I found these stats on Amazon (https://www.amazon.co.uk/BECA-95-240VAC-Programmable-Underfloor-Thermostat/dp/B01NCWL1O7/ref=sr_1_fkmr0_1?ie=UTF8&qid=1503045986&sr=8-1-fkmr0&keywords=becca+16a+thermostat
At just ?54 they seemed like a steal. I wrote to BecaEnergy and asked for the API and they returned it to me in 4 hours ! (blimey!!)
So I bought one, and I leveraged the Heatmiser plugin created by @racarter (thanks Alan! ;D) to create a BecaEnergy Plugin.
The functionality is not as rich as the Heatmiser (basic by comparison) - but reporting ambient temp, setting a Set Point Temperature, and changing Modes - what more do you need?
It works great. Let me know if anyone wants it.
