Andrew from Friday Whisky Mafia picked up one at the Feis Ile. It's going into a tasting later this year, only 14 spots of 50ml each though. I'm looking forward to trying it.
We got these for around the pool, very happy with them.

My system's been running since April 25, shows between 77-80 cycles on the different batteries. Usually get down to about 30% charge everyday and up to about 90% in winter.
Batteries are Sunsync
I use the Sonoff TH20 coupled with a temperature probe(Sonoff WTS01) It's possible to set timer settings however I prefer to set a required temperature for shower/bath time based upon what the probe is reading. You can also turn on/off via the app.
Do you know the wlan0 ip(local ip)? I had a previous issue where I couldn't access SolarAssistant via the internet but I was able to connect to it via the local ip.
