## Description

Ecowitt Wireless Digital Thermometer Hygrometer Monitor - Temperature Humidity Meter, WH31(WN31) LCD Multi Channel Sensor (1 PC) for Home Office : desertcart.co.uk: Business, Industry & Science

Review: Nice add on - Having just bought my Ecowitt HP2564 weather station I was keen to expand the functionality inside the house with further temp / humidity sensors so I can monitor these values around the house. These are really easy to install. Just add batteries and at the same time set the 'jumpers' to which channel number you require and your preference for measurement in F or C. Screw a small screw into the wall (provided, the screw not the wall) and attach using the keyhole on the back and off you go. My HP2560 display picks up the new 'channel' immediately and includes it when auto scrolling through. Job done, no faffing, which suits me fine.
Review: Automatically registered by GW2000A hub, eventually. - Nice, I'm able to track temperatures in many different areas of my house, with my GW2000A hub, for summer cooling and warming trends, and winter cooling and warning trends. I'm experimented with different cooling and heating ideas, which will hopefully show me which cooling/heating ideas work better. Update 2025-11-18 One of my new three is in my chilly loft, with two Ni-MH AA's, another in a outbuilding, with seven of the eight with Alkaline AA's. The signal strength and battery charge telemetry look good for all so far, and will hopefully stay so for many more months. If the loft Ni-HMs last enough, I may switch to using Ni-MHs in all of them, to save having to buy/keep so many spare Alkaline AA's. So, I've got 10 Temperature/Humidity measurement sensor units being logged now, including the hub and WS69; but I'd prefer it if the hubs could support at least 2 more such sensor units. These sensors show the benefits of coverage and various insulation, including Double Glazing, in unheated areas. Fine Offset's, and other kit with regular temperature and humidity logging, made it trivially easy for any rational people, with seeing eyes, to identify, using the Scientific Method, that cloud (water vapour) is the real "greenhouse gas", NOT CO2! This made the criminality of the unscientific, very political, anti-Carbon propaganda, and the consequent fraud, harassment, and unjust enrichment, for decades, blindingly obvious.
