I use these with zigbeefordomoticz https://nl.aliexpress.com/item/1005006097911972.html?spm=a2g0o.productlist.main.35.6e7713795PFwgB&algo_pvid=88f9b0f3-7744-4be5-99aa-7570537db13e&algo_exp_id=88f9b0f3-7744-4be5-99aa-7570537db13e-17&pdp_ext_f=%7B%22order%22%3A%22380%22%2C%22eval%22%3A%221%22%7D&pdp ...

An other solution is to install ZIgbee temperature sensors. They all cost less than 10 euro (even available with nice displays). You only need to install a Zigbee Coordinator and install for instance Zigbee for Domoticz (https://zigbeefordomoticz.github.io/wiki/en-eng/) In the end a much more cost ...

Since this evening buienradar data is being updated with actual data

These temp sensors also work fine:

I use the Shelly Flood in combination with MQTT and ShellYMQTT. Works directly with Domoticz without further hardware.
